WARNING

The vacuum fluorescent displays are made of glass and should be handled with care.

MOUNTING UNIVERSAL DISPLAY SYSTEMS WITH SUBPANELS

When mounting instrumentation systems mounted to an ABS subpanel, begin by removing the subpanel from the aluminum. Cut an opening in the dash just smaller than the outer dimensions of the aluminum panel. Remove all nuts and washers from the studs on the back side of the panel and insert into the hole. Next, install four washers or clips and secure with a nut on each. This is what holds the panel to the dashboard. Now, install a nut on each stud and set the display panel in place over the studs. If the studs were bent slightly inward from securing the aluminum panel, you may have to bend them outward to line up with the holes on the ABS subpanel. Always lay the display panel aside when not in use to avoid accidentally damaging the displays. Once aligned, secure it with an additional four nuts. Leave a gap of no less than 1/8" between the display glass and the front lens material. Be careful not to compress the glass against the front lens. Again, note that the displays are glass and should be handled with care. Use extreme care around the glass evacuation tubes (small tubes at the bottom of each display) as bumping them may cause breakage and render the display useless.

MOUNTING SYSTEMS WITH DISPLAYS MOUNTED TO ALUMINUM

When mounting year specific aluminum panel, cut an opening into the dashboard if necessary and secure the entire panel with the instrumentation using the appropriate mounting hardware. Some panels are set into the front of the dash while others are installed from the rear of the dash. The exact mounting configuration will depend on what year car and panel you are installing.

MOUNTING SINGLE LENS SYSTEMS

Your DAKOTA DIGITAL single lens system will come to you with a single plexiglass lens and instrumentation that is mounted in an aluminum case. The lens and the instrumentation have corresponding mounting holes. After you have affixed the mounting studs of your choice to the backside of your dash, the lens piece should be slid over the studs followed by the display system. The lens can be secured with either washers and nuts, or by a bead of RTV around the back side of the lens and case. If RTV is used, the system will need to be held in place until it has had time to cure. The lens should be tight against the aluminum display case.

Adjust the height of the panel so that the glass displays are 1/8" away from the front lens.

Applying a lock washer and nut to the studs behind the display panel, secure the display panel to the bezel. If screws were provided with the panel, secure them through the display panel and into the bezel. No additional holes should need to be drilled. All holes in the display systems are pre-drilled at the factory.

3 MAN 650066:D

MOUNTING KITS INTO ORIGINAL DASHES

Some kits will include a separate mounting instruction sheet so please see that first for system mounting instructions. Some systems will attach directly to the bezel, and others will mount back into the instrument cans where the factory gauges where mounted. There are three basic system mounting configurations read on to identify your system and how to mount it.

It may be necessary to trim or remove some plastic or bezel material depending on the system.

You may also need the following tools and materials to complete a system install depending on the vehicle

•

Screw drivers

•

Nut drivers

•

Side cutters

•

Die grinder

•

Cut off wheel

•

Silicone / RTV

Complete Systems mounted in new bezel

If your system came from Dakota Digital with a new bezel, installation on the system should be straight forward. Remove the factory gauges and bezel and install the new one.

Systems that have a glue-in lens (loose lens with no mounting holes in it)

If your system included a front lens separate from the displays and contains no mounting holes, you have a glue-in lens system. The lens will be secured to the original bezel using RTV.

When installing the display system into the original bezel, several steps must be taken to prepare the bezel. The first is to remove the cluster from the dashboard. Next, remove all instrumentation from the bezel as well as the factory lens. You will generally be left with a bare plastic or metal bezel. Remove any felt inserts from the back side of the bezel that sit between the lens and the bezel.

Next, take the supplied lens, remove any masking that may be on it and with the lettering facing the front of the dash, place it in the bezel. Lay a bead of RTV around the back side of the lens to secure it in place. After the RTV has cured, the display panel is ready to be placed on the bezel. If studs were supplied with the panel, screw them into the bezel and place a nut on them before placing the display system on it.

Systems that mount into original cans with hardware (lens and systems screw together)

If the system came with the lens and system attached together, the compete assembly should either mount into the original cans or secure directly to the bezel. Some systems may come with a new can or housing over the back of the system that should make mounting very apparent. If you have a version with a system and lens attached to ABS plastic, you will need to secure these to the original cans or instrument housings.

First, remove the cluster from the dashboard. Next, remove all instrumentation from the bezel as well as the factory lens. You should essentially be left with a bare bezel, possibly reusing any clear lenses that were covering the factory gauges. If you have a system that came in a new can or has an ABS subpanel that fits over the factory bezel, you can secure it back to the bezel and re-install into the car.

If your system mounts into the cans, continue removing the stock gauges as well as other lights and loose parts from the instrument cans as the display systems typically sit flat into the can so everything must be removed. Once the cans are cleared, the system should fit into the can and secure from the back of the can with screws. The ABS sub-panel should have some mounting holes and supplied hardware for securing the system to the can. Once system is secure, reattach cans to the bezel and re-install into the car.

CONTROL BOX MOUNTING

Once the display panel is in place, mount the control box within reach of the ribbon cable on the display panel (approximately 3 feet). Pick a mounting location that will allow you access to wire all of the inputs on the control box. Double sided tape, hook and loop fasteners, or screws in the two tabs on the case work fine for securing the control box under the dash.

When selecting a mounting location, avoid placing the control module next to, or just opposite of the firewall, from ignition components, ie: Ignition coil, HEI, etc. Ignition components can emit tremendous amounts of electric noise, affecting the operation of electrical components.

Wiring the control box into the vehicle

While the control box contains several connections, the wiring is straightforward.

Depending on how many auxiliary functions you want displayed, not every terminal will be used in most applications. Below we describe the function of each terminal, what they do, and how to wire them.

TERMINAL DESCRIPTIONS

Status LED

This LED is located at the corner of the control box, next to the GROUND terminal. The

LED is used for diagnostics.

•

A steady flash, on and off, about one second apart indicates the system is powered and operating normally.

•

On steady indicates low power, below 9V, at the POWER terminal (the displays will also generally be dim) .

•

Not flashing or lighting indicates loss of power or ground.

GROUND

This is the main ground for the display system. A wire should be run from this terminal to the vehicle’s main chassis ground . Use 18 AWG or larger wire to ensure sufficient grounding.

Proper vehicle grounding is extremely important for any gauges (or electronics) to operate correctly. The engine block should have heavy ground cables to the battery, frame, and firewall. Failure to properly ground the engine block or the control box can cause

incorrect or erratic operation.

8 MAN 650066:D

POWER

Connect the POWER terminal to accessory +12V power from the fuse panel or vehicle wiring harness. This terminal should have power when the key is on or in accessory position.

In addition to powering the display system, this is also where the voltmeter gauge senses the vehicle electrical system voltage. The supply source should be a fused 5 - 20 amp circuit, the system only draws about 1 amp, so sharing an existing accessory circuit will be generally be fine.

Use 18 AWG wire to ensure the system receives a sufficient power feed.

*** Never connect this to a battery charger alone. It needs to have a 12 volt battery connected to it. Battery chargers have an unregulated voltage output that will cause the system to not operate properly and may cause damage to the control box.

TACH

Depending on the type of instrument system that you have, there may be a bar graph tachometer, a digital tachometer, or both. Connect the TACH terminal to the ignition system.

On vehicles using a separate ignition coil, connect to the negative side of the coil. The negative side of the coil will be the wire that goes to the points or electronic ignition module. For GM HEI ignition equipped motors, connect to the terminal marked “TACH” or on some systems a single white wire with a spade terminal on it. On some aftermarket ignition systems, connect to the

TACH output terminal. On computer controlled ignition systems consult a service manual for the wire color and location. With a magneto system, connect to the kill wire for the tach signal.

Do not connect the TACH terminal to the secondary, or high voltage side of the ignition coil.

To ensure that the ignition system does not interfere with any other dashboard functions, do not run the tachometer wire alongside any other sender or input wires. DO NOT USE SOLID

CORE SPARK PLUG WIRES WITH THIS DASHBOARD SYSTEM. Solid core ignition wires cause a large amount of electromagnetic and radio frequency interference which can disrupt the system operation.

The tachometer is compatible with almost all gasoline engines. The engine cylinder selection, display update rate, tach signal type, and rpm warning point can be adjusted in the setup menu under “ TACH ”. If a diesel engine is being used then you will need a tach interface, such as Dakota Digital’s DSL-1 or DSL-2. Be aware of the cylinder setting when using computer outputs or reading the tach signal from an ECU. GM LS1 engines require the tach to be set up for a 4 cylinder, low voltage signal when reading from the ECU even though it is a V8 engine.

WARN

The WARN terminal is an output for a relay or small light. The output is ground-activated when the preset rpm limit is exceeded. This output can turn on a 4 Watt or smaller 12 volt bulb or can activate a relay to turn on a larger bulb. To wire a warning light to this output, connect one wire from the bulb to 12 volt accessory power and connect the other wire to the WARN terminal.

DIM

The gauges are designed to dim down when the headlights are turned on. This is to reduce the display intensity at night so the gauges do not cause eye strain or reduced night vision. Connect this to the tail light or parking light circuit so that it has 12 volts whenever the headlights are on. When this terminal does not have power the display system will be at full brightness. When power is applied, the display dims to an adjustable level.

The night brightness level is adjustable two different ways. This preset brightness is adjusted in the setup menu “ NIGHT ”. See ADJ SND for a description of the second method.

By default the system will dim to a about ½ bright ness when DIM terminal gets +12V.

9 MAN 650066:D

SPD +

This terminal is used to supply power to Dakota Digital speed sensor SEN-01-5. This supplies 5V DC to the sensor and should not be hooked up to anything else. Connect the red wire from the SEN-01-5 to this terminal.

If you are using a 1-wire VSS output from a computer or a two wire pulse generator this terminal should be left open.

***DO NOT use this terminal to power any other devices it is a low current +5V output.

SPD SND

This is where the vehicle speed sensor (VSS) connects. The signal supplied to this terminal will be used by the control box to calculate the speed reading on the display and also for calculating and saving odometer mileage.

Dakota Digital supplies a 3-wire sensor for most of its kits, SEN-01-5. If you are using this sensor, the white wire is the speed signal; connect to SPD SND. The red and black wires in the cable are power and ground (5V DC) and their connection is discussed in SPD + and SPD -.

For two wire speed sensors such as a cable driven pulse generator, the polarity of the wires does not matter. Connect one wire to the SPD – (Ground) and the other to the SPD SND terminal. The speed sensor ground wire should be brought back to the control box to ensure a proper signal is received. Twisting the ground and signal wires around each other provides an additional level of interference protection. The speed signal wire should not be routed alongside tach, ignition, or other high current or high voltage wires.

For vehicles which have a vehicle speed signal from a transmission sensor or ECM, tap into the VSS wire and connect it to the SPD SND. Consult a vehicle service manual or wiring diagram to determine wire color and location.

This system can accept 4000 ppm – 128,000 ppm speed signals with room for adjustment. The speedometer is fully adjustable and calibration is discussed in a later section.

***Failure to calibrate the speedometer may cause your odometer mileage to increase very rapidly if the speedometer is reading too fast.

*** The speed signal wire should NOT be routed alongside ignition or other high current/voltage wires.

SPD –

This terminal is used for speed sensor ground. This insures a proper ground as well as providing proper hook-up for a twisted pair of wires, or a solid state sensor. Only ground the speed sensor here. If you are using a single wire output from a computer for the VSS then this terminal should be left open.

SPD OUT

This terminal can be used to supply a speed signal to auxiliary devices such as a cruise control or radio volume adjustment. The output is scaled to the input speed signal coming into the SPD SND terminal. It can be set to 2000 PPM or 4000 PPM.

***If you are using the bus speed signal option this output will NOT work.

SW 2 (-) or Tach switch

The SW 2 terminal is used for selecting the various rpm, engine, and warning displays and also for entering the demonstration mode. The SW 2 input is activated by a ground connection. The push button switch supplied (or any momentary normally open switch) is wired by connecting one terminal to SW 2 and the other terminal to a ground. When the button is pressed and released, the tach message display will change. When the button is pressed and held for a few seconds, any re-settable information displayed will be zeroed. On systems with two message displays, the one below the tach is dedicated to rpm/warn messages. On

10 MAN 650066:D

systems with one message display the speed/performance and rpm/warn messages will use the same display.

To enter DEMO mode, press and hold switch 2 while turning the key on. The system will light up and say DAKOTA DIGITAL on the message readouts, release the switch and the system will stay in demo mode until the power is cycled off and back on without the switch held.

SW 1 (-) or Speed switch

The SW 1 terminal is used for selecting the various speed, distance, and performance displays and also for entering the setup menu. The SW 1 input is activated by a ground connection. The push button switch supplied (or any momentary normally open switch) is wired by connecting one terminal to SW 1 and the other terminal to a ground. When the button is pressed and released, the speed message display will change. When the button is pressed and held for a few seconds, any re-settable information displayed will be zeroed. On systems with two message displays, the one below the speed is dedicated to speed/performance messages.

On systems with one message display the speed/performance and rpm/warn messages will use the same display.

ADJ SND

The ADJ SND terminal is an optionally used input that allows you to have control over the dimming brightness. By default, the system will dim to approximately half brightness when the

DIM terminal has power, +12V, but this level is adjustable in the NIGHT setup menu. Using the

ADJ SND terminal allows you to have a dash mounted control to vary the brightness while the headlights are on. This requires Dakota Digital’s DIM-1 kit; a stock headlight rheostat will not work.

The DIM-1 has two wires, one connects to the ADJ SND terminal and the other connects to ADJ - ground. The dash mounted dimmer will only vary the display brightness when the DIM terminal has power, +12V.

ADJ –

This terminal provides a ground reference for the optionally installed DIM-1 for dash mounted dimming control. One wire from the potentiometer will connect to the ADJ – terminal, the other connects to the ADJ SND.

*This terminal should not be used for grounding other sensors or devices or damage to the control box will occur. If not using a Dakota Digital DIM-1, this terminal should be left open.

WTR SND

The water temperature sender included with this system must be used. Other senders will cause incorrect readings or damage to the control box.

The supplied sensor, Dakota Digital SEN-04-5, is a 100-300ºF(40-150ºC) temp sensor.

The sender mounts on the engine block or into the intake manifold so that the end of the sensor is in the engine coolant flow. It has 1/8” NPT threads, adaptor bushings may be used to adapt it for various applications.

The water temp sensor has two wires coming from the harness. One wire will connect to the WTR SND terminal; the other wire will connect to the WTR –. It does not matter which wire goes into either location.

Due to the construction of the sensor, readings at lower temperatures below 100 ºF will be inaccurate. The sensor is designed to be accurate from approximately 100 ºF - 300 ºF.

11 MAN 650066:D

WTR –

This is the ground reference used for two-wire water temp sensors. This will connect to one of the wires from the Dakota Digital SEN-04-5. The other wire will connect to the WTR SND terminal, and it doesn’t matter which wire goes into either location.

OIL +

This terminal is used to supply power to Dakota Digital pressure sensor SEN-03-8. This supplies 5V DC to the sensor and should not be connected to anything else. Connect the red wire from the SEN-03-8 to this terminal.

***DO NOT use this terminal to power any other devices it is a low current +5V output.

OIL SND

The oil pressure sender included with this system must be used. Other senders will cause incorrect readings or damage to the control box.

The supplied sensor, Dakota Digital SEN-03-8, is a 0-100 psi solid state pressure sensor. The sender can mount on the engine block or in an oil pressure line off of the block.

The sender has 1/8” NPT threads. Adaptor bushings may be used to adapt it for various applications.

The oil pressure sensor has three wires coming from the harness, plus one bare shield wire. The WHITE wire will connect to the OIL SND terminal, the RED to OIL + (5V DC), and the black and bare shield wire to OIL –. Do not route the oil sender wire alongside a spark plug wire or other high current or high voltage wires. Doing so can cause incorrect or erratic gauge readings.

If the oil pressure drops below an adjustable warning point, the reading will flash as a low oil pressure warning. The default warning point is 10 psi. If the oil display shows “—“ this indicates that the control box is sensing a short to ground or out-of-range error from the sender or sender wire. If the oil display shows “ EEE ” this indicates that the control box is sensing an open circuit or out-of-range error from the sender. If either indication remains on the display, inspect the sender wire for damage, check the routing of the sender wire, check the sending unit grounding, and check that the correct sending unit is connected.

OIL –

This is the ground reference used for three-wire pressure sensor. This will connect to the black wire as well as the bare silver shield wire from the Dakota Digital SEN-03-8.

***The bare wire is the shield wire, connect this wire to the OIL – along with the black wire

***DO NOT connect this terminal to any other devices

FUEL +

This output is not typically used. It is a low current +12V supply for powering solid state fuel sensors. Currently, it does not have an application for any Dakota Digital fuel level sensors.

***This terminal should not be used with a typical resistive type fuel sensor. For most applications, leave this terminal open. Do not try to power other devices from this terminal or damage to the control box will occur.

12 MAN 650066:D

FUEL SND

The fuel gauge sending unit is not normally supplied because the display system can use the existing fuel sending unit that is already in the tank in many cases. The sending units that are compatible with this system are as follows: GM, Ford, VDO, and Stewart Warner. It is also possible to program in a custom setting for senders that are not pre-programmed into the system.

Dakota Digital recommends that you run two wires back to the fuel level sensor to insure proper grounds. Use the FUEL - and FUEL SND terminals and run a twisted pair of wires back to your fuel level sensor. Connect the FUEL - terminal to the fuel level sensor body or a mounting screw to insure the sensor is sufficiently grounded. The other wire is the sensor signal which goes to the FUEL SND terminal.

If your wiring harness already has a single wire routed through the vehicle for the fuel sender then it may be used. If using a wire from an existing harness, make sure that the wire does not have power. The fuel sender gets power from the control box only. Fuel senders reference their ground from the sender mounting plate. Make sure that a ground wire is connected from one of the sender mounting bolts to the vehicle frame.

The fuel sender type is selected using the setup menu under “ FUEL ”. The settings are discussed later in the setup section. Anytime the fuel level is below 10%, the reading will flash as a warning of low fuel.

The fuel gauge will initially display “ FL ” until the fuel sender type has been set. If the fuel display shows “ -” this indicates that the control box is sensing a short to ground or out-ofrange error from the sender or sender wire. If the fuel display shows “EE” this indicates that the control box is sensing an open circuit or out-of-range error from the sender. If either indication remains on the display, inspect the sender wire for damage, check the routing of the sender wire, check the sending unit grounding, and check that the sender selection is set correctly for the sending unit that is connected.

FUEL –

This terminal is used to provide a ground connection for the fuel level sensor. Dakota

Digital recommends that you use the FUEL - terminal and run a twisted pair of wires back to your fuel level sensor. Connect the FUEL - terminal to the fuel level sensor body or a mounting screw to insure the sensor is sufficiently grounded. One terminal on the sensor is the signal which goes to the FUEL SND terminal

***For fuel level sensors that are attached to an electric fuel pump, or if you have an electric fuel pump in the tank, make sure that the fuel pump is externally grounded to the vehicle chassis. Attempting to ground the fuel pump to the Dakota Digital control box will result in erratic operation and damage to the control box.

CRUISE (-)

The CRUISE terminal can be used as a “cruise engaged” indicator. The CRUISE input is activated by a ground signal from a compatible cruise control harness. Whenever the CRUISE input is grounded, the system will display a small “c” to the right of the speedometer.

WAIT (+)

The WAIT terminal can be used as a “wait to start” or glow plug indicator. The WAIT input is activated by a 12 volt signal from the glow plugs. Whenever the WAIT input is powered,

+12V, the system will display “ WAIT ” on the tach message display. This message can be cleared by pressing and holding switch 2, or once the WAIT terminal loses the +12V signal.

13 MAN 650066:D

GEAR (1 wire)

The GEAR terminal is used for the gear shift indicator. The indicator is built into every system, but will not light up unless a Dakota Digital GSS-1000/2000/5000 gear shift sending unit is connected, telling the system what gear the transmission is in. The gear shift sending unit is not included with the system and must be purchased separately if desired.

The GEAR terminal will connect to the FIRST terminal on a GSS-1000 or to the 1-WIRE terminal on a GSS-2000 or GSS-5000. Follow the instructions in the GSS manual for use with a single wire display system. When the gear shift sending unit is connected, the gear name will be shown on the tach message display.

NOTE: The system will automatically change to the gear display for a few seconds whenever the gear position changes, even if viewing a different message display.

4x4 (-)

The 4x4 terminal can be used on four wheel drive vehicles. The 4x4 input is activated by a ground signal from a switch on the transfer case. Connect a wire from this terminal to the switch on the transfer case. Whenever the 4x4 input is grounded the system will display “ 4W

DRV ” on the message display. When signal turns off, the system will briefly display “ 2W DRV ” on the message display.

RIGHT (+)

The RIGHT terminal is activated by a 12 volt signal from the turn signal flasher. When this terminal has 12 volts, an arrow will light up to the right of the speedometer display. An existing wire from the vehicle for the right turn indicator can be used or a new wire can be connected from the turn signal flasher or power wire feeding the right turn signal bulb.

LEFT (+)

The LEFT terminal is activated by a 12 volt signal from the turn signal flasher. When this terminal has 12 volts, an arrow will light up to the left of the speedometer display. An existing wire from the vehicle for the left turn indicator can be used or a new wire can be connected from the turn signal flasher or power wire feeding the left turn signal bulb.

HIGH (+)

The HIGH terminal is activated by a 12 volt signal from the headlight high beam wire.

When the terminal has 12 volts, an indicator will light up to the lower right of the speedometer display. An existing wire from the vehicle for the high beam indicator can be used or a new wire can be connected from the high beam side of the hi/low beam switch.

BRAKE (-)

The BRAKE terminal can be used as a brake system warning indicator. The BRAKE input is activated by a ground signal from the brake pressure switch on the master cylinder or from the parking brake set switch. Connect a wire from this terminal to the pressure switch on the master cylinder or consult a vehicle service manual to determine color and location of an existing wire. Whenever the BRAKE input is grounded, the system will display “BRAKE” on the message display. This message can be cleared by pressing and holding switch 2.

14 MAN 650066:D

CHECK ENG (-)

The check engine terminal is used with fuel injection ECM’s to display engine problems and trouble codes. The CHECK input is activated by a ground signal from the ECM. Whenever the check input is grounded, the system will display “ENGINE” on the message display. This message can be cleared by pressing and holding switch 2.

When the ECM is placed into diagnostic mode, trouble codes can be read by counting the flashes. Consult a service manual for the fuel injection system that you have for further information on trouble codes.

With some ECM’s, a 12 volt light bulb may need to be connected in addition to the

CHECK input in order to provide proper current loading. In this case, both the bulb and our display system indicator would come on when the check engine wire is “active”.

SPEEDOMETER SETUP/CALIBRATION

There are two main methods for calibrating the speedometer, auto cal and adjust. Auto cal requires that you have one measured mile marked out (1 km for metric). Adjust requires you to follow another vehicle going at a set speed, using a handheld GPS with speedometer function, or timing yourself over a mile to determine your speed.

* Dakota Digital recommends you start with the Auto Cal method to get the speedometer close. If you find it’s reading too fast/slow after the Auto Cal, then attempt the Adjust mode.

•

Press and hold SW1, then turn the key on and start the engine.

•

Once the engine is running, release SW1. SE SPEED should be displayed.

•

Press and hold the switch until is displayed to go into the speed setup menus,

• release SW1.

Now you can press and release the switch to scroll through the sub-menus, “ sender ” “ auto ”

“ adjust ” “ S ” “ output ” “ DONE ”. When you get to the desired sub-menu press and hold the switch to select it.

Speed sensor setup ( SENDER )

This menu is used to set the speed sensor input type. You can use the supplied pulse generator or existing speed sensor for most applications. You can also read the speed signal with the use of a future product called the bus interface module (BIM). Dakota Digital also offers

BIM that will allow you to read the speed signal from an ECU if you are installing the system in a vehicle equipped with the OBDII port or a drivetrain from a newer vehicle, most 1996 and newer vehicles have this.

If you are using a Dakota Digital pulse generator or feeding an ECU signal into the SPD

SND terminal, this is considered a “ normal

Auto Cal ( AUTO )

This menu is used to calibrate the speed signal by driving a measured mile (or kilometer)

•

When “ AUTO ” is displayed press and hold SW1 until you get “ ”

•

Release SW1 and the primary speed unit will be displayed

•

Press and release SW1 to toggle between “ MPH ” for miles per hour or “ KMH ” for kilometers per hour. The setting saved here will be what the speedometer reads as well as the

units used to calculate odometer mileage.

•

When the desired unit is displayed press and hold SW1 until you see the “ ” then release

SW1.

The speedometer will display “ CAL ” and the odometer should be reading “ 000000 ”, the other displays should be lit and display normally(fuel, volt, water, and oil). Begin driving the measured mile. The odometer reading should start incrementing as you travel, indicating the pulses received from the speed sensor or VSS. This is known as the pulses per mile (PPM).

Once you reach the end of the marked mile, or are passing the marker, press and release SW1.

The displays will flash off, then everything should light up and the speedometer should now be displaying your speed. Auto Cal is now complete and your speedometer should be reading correctly.

17 MAN 650066:D

(Auto Cal continued)

NOTES: You do not have to drive at a constant speed nor do you have to avoid stopping during Auto Cal. When completed, you do no need to stop, you may, but you can also

just press and release SW1 as you pass the 1 mile mark.

The message display cannot be used to determine when the mile has been driven, it’s only there as a reference to indicate pulses are coming into the control box. Even if you have an 8000 PPM sensor you may calibrate at 9xxx PPM (for example) due to gearing

and tire size.

Also be aware that the odometer miles are calculated from the speedometer cal value; if it is not calibrated properly, the odometer miles could be higher/lower than actual.

***If you do not receive more than 2000 pulses during calibration the unit will error out.

Adjust Mode ( A )

•

Adjust is different depending on what input signal is selected in the SENDER menu.

When “ ADJUST ” is displayed, press and hold SW1 until you get “ ” then release the switch.

•

Now select the primary units by pressing and releasing SW1, “ MPH ” for miles per hour or

“ KMH ” for kilometers per hour.

•

When the desired units are selected, press and hold SW1 until you see the “ ” then release

SW1.

If “ normal is selected for the sender type it will allow you to adjust the signal that is being supplied to the SPD SND terminal coming from a pulse generator or ECU. The fuel, volt, oil, water, and tach will operate normally. The speedometer will show the speed reading and the speed message display will say “ ADJUST ”. Begin driving at a known speed. Press and hold

SW1 to increase the speedometer reading the next press and hold of SW1 will decrease the speedometer reading. You can continue adjusting up and down as needed until the reading is correct. When the speedometer is correct, stop and restart the system, by turning the key/power off and then starting the vehicle back up. The new calibration will be saved when the power is shut off.

If “ Bus ” is selected for the sender type, the speed signal should be coming into the AUX

I/O port through the use of a future BIM module. The adjustment ratio ranges from 75 – 125% on this setting as it is assumed that the signal from the external device is the correct pulse rate, there is only provisions for slight adjustment. The odometer will light up and show “ CL xx ” xx is adjustable from 75 – 125 and is the percentage the input is corrected by. If set to 100 the signal is uncorrected and whatever the BIM module is reading is displayed on the dash.

NOTES: For adjust mode you can follow another vehicle, time yourself, or use a GPS as a

reference. A chassis dyno is another excellent way to use the Adjust mode.

Also be aware that the odometer miles are calculated from the speedometer cal value, if calibrated properly, odometer miles could be higher/lower.

Service countdown meter ( S SET )

The service countdown meter or, S-SET, allows you to set a mileage value that will decrease as the odometer miles increase. When the value gets to zero, a message “ S DUE ” will appear on the message display on power up to remind you that service is due. This can be used for routine maintenance reminders such as oil changes.

•

When “ S SET ” is displayed press and hold SW1 until you get “ ” then release the switch.

BUS INTERFACE MODULE SETUP

The bus interface modules (BIM) are a future product added to Dakota Digital instrumentation systems. They allow you to add auxiliary gauge functions, such as fuel pressure, vac/boost, trans temp, etc., right into the system without having to add additional gauges. All of the BIM readings are displayed on the tachometer message display where the tachometer and other performance readings are currently displayed. Switch 2 (SW2) is used to cycle through the various message screens.

More detailed instructions are supplied with the BIM units.

INFORMATION MENU

The information menu, “I ” is used to display software code information should you have any troubles, this information can be useful for troubleshooting as well as the current speedometer calibration value if using the normal speed input (SPD SND).

Release the switch and the odometer will show the current PPM setting/calibration value.

•

Press and release the switch to go on to the next setup menu.

ODOMETER PRESET MENU

The control box will allow you to set the odometer miles to match your current odometer reading, ONE time within the first 100 miles. Once the odometer has more than 100 miles, this menu option will no longer be displayed. Make sure you have correctly selected the units to be either MPH or km/h and calibrated your speedometer first. The odometer will be set in the selected units. Once you have preset the miles you cannot change it again

without sending to the factory.

WARNING!!: This only allows setting odometer to the nearest mile. Do not use tenths!

For example a mileage of 65432.1 should be set to “ 065432 ” using this method. If the

tenths digit is used, the odometer will read 10 times too high.

TROUBLESHOOTING GUIDE

This is a list of some problems and their solutions which may be encountered when installing your instrumentation system. If you cannot determine what the problem is or how to solve it, please call our technical assistance line (605) 332-6513 or email [email protected].

* A note on vehicle grounding. *

The most common cause of problems with electric gauges and other sensitive vehicle electronics is poor ground connections. The engine block has the highest ground currents of any point in the vehicle. The ignition system, electric gauge senders, starter, alternator, etc. all use the engine block for a ground point. Since the alternator is grounded directly to the engine block, all ground currents in the entire vehicle must pass through the engine block while the engine is running. A weak or loose connection can cause many unexpected problems that may be difficult to track down. The engine block should have heavy ground straps to both the chassis and the body. The main negative cable from

the battery should be connected directly to the engine block.

Clock Instructions

For VFD systems with a clock built in

If you purchased your instrument system with an optional clock, it must be wired separately. The clock displays the current time in 12 hour format. The digital clock from Dakota Digital incorporates the reliability and quality of our standard gauges. These features include:

•

Quartz accuracy

•

Night dimming feature

•

Very low standby power to prevent battery drain

•

High visibility VFD display for sunlight readability

Wiring:

Clock

BLACK

RED

Connect to a good ground point in the vehicle

Connect to switched 12 volt power point

(An accessory terminal will work for this)

ORANGE Connect to a constant 12 volt power point

(This will keep the correct time)

BLUE Connect to the taillight circuit

+12V when lights on for dim function

Operation:

The gauge needs the red, orange, and black wires connected to operate. The red wire should have switched 12 volt power from an ACC. point on the fuse panel. The orange wire should have constant 12 volt power. The black wire should be connected to a good ground point. When the blue wire has 12 volts, it will dim the display for night viewing, this may be wired along with the wire to the DIM terminal on the control box.

30 MAN 650066:D

Setting the time

Through lens:

Using a small, thin object such as a pen or hairpin, press “set” buttons through front lens access holes.

The access holes are on the right side of the lens. Top “set” button advances hours, bottom “set” button advances minutes.

Remote switches:

Some systems may have two push button switches for setting the time. These switches can be mounted anywhere for easy access. They are provided on system where the holes in the lens may not be accessible. The switches are just momentary push buttons, a press and release will either advance the hours or minutes. The

BLACK “set” button advances hours, the RED “set” button advances minutes. Each time that you make a change to either the hours or minutes, the seconds are reset to zero.

Adjusting the accuracy:

The clock is accurate to +/-2 minutes a month as it is set, but it can be tuned for better accuracy if desired.

Press and hold both of the set buttons for several seconds. The clock will display “C 0”. The “C” indicates that it is in the calibration mode and the second number is the current calibration value. The calibration value indicates the number of seconds to add or subtract each day. The clock can be adjusted from +7 sec/day to -7 sec/day.

Press the minute set button to change the cal value. Press the hour set button to return to normal clock operation.
