IntelliStart Always exercise good judgment and common sense

The IntelliStart accessory is designed to be used ONLY on a fuel-injected, gasoline powered vehicle
with an automatic transmission. Installing IntelliStart on a vehicle that has a manual transmission poses
an EXTREME SAFETY RISK! Never install a Clifford remote engine starting product on a manual transmission vehicle.
Always exercise good judgment and common sense
when using the remote starter:
NEVER install the system on a manual transmission vehicle.
NEVER remotely start the vehicle in an enclosed area
without sufficient ventilation.
NEVER allow anyone access to the remote controls
while installing or servicing.
NEVER install the system without a hood pin switch.
In case of transmission slippage, NEVER remotely start the engine
if you or someone else is directly behind or in front of the vehicle.
1. The module MUST be installed in the passenger compartment, not the engine compartment.
2. Pick up the starter, ignition and heater/AC wires in the wireloom off the ignition key to ensure that the starter wire is
connected before the vehicle’s neutral safety switch (to prevent the engine from starting while in gear).
3. DO NOT EXTEND the WHITE/BLUE, WHITE/BROWN, GRAY or WHITE/GREEN wires. They can be shortened,

Passenger Compartment Components
Control Unit
The control unit must be mounted in the passenger compartment, NOT in the engine compartment. Identify where the
control unit will be installed. Route wires from this point, leaving slack in the wiring for ease of service. Do not plug the
connectors into the module until installation is complete.
Wiring the Brake Lights
CAUTION: IntelliStart monitors the brake light to prevent an unauthorized driver from driving the car
and to switch to normal engine operating condition. The brake light input wire (BLUE/WHITE) MUST be
connected and the brake light MUST be in working condition or IntelliStart will not operate properly.
1. Turn the ignition on and press the brake pedal to make sure the brake light turns on.
2. Connect the black lead of the voltmeter to ground and set the dial to DC volt.
3. Probe the wire on the center terminal of the brake light with the voltmeter red lead. The voltmeter should read +12V
when you press the brake pedal; 0 volt when released. If no signal is detected, try the other wire.
4. Connect the BLUE/WHITE wire to the brake wire.
Wiring the Parking Lights
IntelliStart uses the parking lights as a visual acknowledgment of the engine starting process and for continuing visually
confirmation that the engine is running under IntelliStart’s control. A relay is built into the control unit for supplying
power (+12V) to the parking light circuit. No external relay is required.
1. Connect the voltmeter black lead to ground, set the scale to DC volt.
2. Probe one of the parking light wires with the red test lead.
3. The meter should read +12V when the parking lights are on; 0 volt when off.
4. Temporarily connect fused +12V to this wire to verify all the parking lights turn on.
NOTE: If only one side of the parking lights turn on, repeat steps 1-4 to locate the second parking light
5. Connect the BROWN wire to the parking light supply wire.
a. If the left and right parking lights are on different circuits, run two leads off the BROWN wire and insert a #46-005
diode in each of the two lines (the diode bands must point toward each light).
Wiring the Channel 2 Input
1. Connect the GRAY/VIOLET wire to the alarm’s channel 2 output (GRAY/VIOLET on Clifford systems).
Wiring the Sensor Interrupt
IntelliStart will interrupt the alarm’s sensor signal when the engine is remotely started (otherwise the alarm would false
upon remote starting).
NOTE: This is not required on Concept, IntelliGuard-IQ and IntelliVoice systems.
1. Cut the alarm’s sensor line (ORANGE on Clifford systems).
2. Connect IntelliStart’s ORANGE/WHITE wire to the alarm’s sensor input.
3. Connect IntelliStart’s ORANGE wire to the sensor’s output line.
General Motors VATS/PassKey Interface
If working on a GM vehicle that has the VATS/PassKey starter lockout, which has a resistor pellet on the ignition key,
you will need to make measurements and connections noted in TechTip #9514 in the TechTips section of this binder.
Wiring the Starter
The WHITE/GREEN wire connects to the switch side of the starter wire. The WHITE/BLUE wire connects to the starter
solenoid side of the starter wire.
NOTE: ALWAYS connect the starter wires between the neutral safety switch and the alarm’s starter
disable relay (if present) or ignition switch (see the diagram). The best location is in the ignition switch
wiring harness.
Locate the vehicle’s ignition switch wiring harness.
Connect the voltmeter black lead to ground and set the dial to DC volt.
Probe for the one wire that carries +12V during the cranking cycle only.
Cut the wire and attempt to start the engine; it should not crank.
Connect the WHITE/GREEN wire to the switch side of the starter wire.
Connect the WHITE/BLUE wire to the starter solenoid side.
Wiring the Ignition
The IntelliStart 14-gauge WHITE/BROWN ignition wire must be connected directly to the vehicle ignition circuit at the
ignition switch wire harness. The 18-gauge WHITE/BROWN ignition wire must be connected to the alarm’s ignition
sense line.
1. Locate the ignition switch wireloom.
2. Connect the voltmeter black lead to ground and set the scale to DC volt.
3. With the ignition key off, probe the ignition wire. The meter should read 0 volt.
4. Turn the ignition key on (indicated by all dash lights turning on). The meter should read +12V and remain at +12V
throughout both cranking and engine running cycles.
5. Cut the wire and try to start the vehicle. The engine should crank, but should not start. If the vehicle starts, reconnect
the wire and repeat steps 3-5.
6. Connect the 14-gauge WHITE/BROWN wire to the ignition wire.
7. Connect the 18-gauge WHITE/BROWN wire to the alarm’s ignition sense line (WHITE/BROWN on Clifford
Wiring the Heater/Air Conditioner
The heater/AC output is for powering the vehicle’s heater/AC system during the remote start cycle.
1. Turn the vehicle’s heater/AC switch on and rotate the ignition key toward “START” one step at a time. Observe at
which position the blower comes on. Turn off the engine.
2. Connect the voltmeter black lead to ground and set the dial to DC volt.
3. Probe for the one wire that carries +12V only when the ignition key is at the position where the blower activates.
4. Cut the wire and start the engine. The blower should not operate.
5. Connect the GRAY wire to the heater/AC wire.
Engine Compartment Components
Hood Switch
As a safety measure, the hood switch prevents the vehicle from starting when the hood is open. When the hood is open,
the system will respond with one flash of the parking lights instead of two and will not start the engine.
1. Select an unobtrusive location for the hood switch.
2. Verify you have adequate clearance to accommodate the switch.
3. Drill a 5/16" mounting hole.
4. Mount and wire the hood switch.
5. Connect the WHITE/BLACK wire to the hood switch.
RPM Monitoring
IntelliStart provides the following four easy installation options:
1. First choice - Optional RPM Monitoring Module #60-521
a. Locate the coil wire that connects to the distributor and attach the RPM Monitoring Module to the coil wire.
b. Connect the RED, BLACK and WHITE wires in the gray shielded cable to the RED, BLACK and WHITE wires of
the RPM Monitoring Module.
2. Second choice - Negative coil
a. Locate the negative terminal of the ignition coil, normally marked (-) next to the terminal.
b. Connect the WHITE shielded cable wire to the negative coil terminal.
c. Individually insulate (tape) the unused BLACK and RED shielded cable wires.
3. Third choice - Fuel injector wire
a. On many engines with electronic fuel injection, there are two wires going to each cylinder: a fuel-injector wire and
a common ignition wire. The ignition wire is usually the same color at each cylinder (and may also be the same
color as the ignition line you tapped into at the steering column).
b. Connect the WHITE wire one of the OTHER wires at one of the cylinders (i.e., NOT the common-color ignition
c. Individually insulate (tape) the unused BLACK and RED shielded cable wires.
4. Fourth choice - On some cars (mostly older GM vehicles) there is a tachometer terminal at the distributor
a. Locate the tachometer terminal (which may be marked “tach”) on the distributor cap.
b. Connect the WHITE wire to the tachometer terminal.
c. Individually insulate (tape) the unused BLACK and RED shielded cable wires.
Power Connections
The two RED wires must be connected directly to the battery’s positive terminal and the black wire directly to the
battery’s negative terminal. If you must extend the heavy gauge RED battery wire, use 12-gauge or larger wire to ensure
proper system operation.
1. Route both RED wires and the BLACK ground wire from the system to the vehicle battery. DO NOT connect the
RED wires together. The RED wires must be individually routed to the battery.
2. Connect the 5-amp fuse and fuseholder to the thin 18-gauge RED wire.
3. Connect the two 20-amp fuses and fuseholders to the heavy 12-gauge RED wire.
4. Connect all fuse holders to the +12V battery lug without removing the battery terminal from its post (remove the
terminal bolt without removing the terminal clamp, slip two ring connectors over the bolt, then retighten).
5. Connect the module’s BLACK wire to the negative (-) battery lug without removing the battery terminal from its post.
Final Connections and Mandatory Programming
1. First connect the 14-pin connector to the IntelliStart control unit.
2. Then connect the 6-pin connector.
3. Perform the MANDATORY RPM PROGRAMMING procedure noted below.
The idle RPM level must be programmed or IntelliStart will not operate properly:
1. Start the engine with the starter/ignition key and allow it to run at least five minutes until the engine has warmed up
and the RPM stabilizes at its normal idle speed.
2. Turn the ignition off, then restart the engine with the key.
3. Within 10 seconds, tap the WHITE wire to ground 3 times.
4. Wait at least 15 seconds while the engine idles, do not push on the gas pedal.
5. Turn the engine off. RPM programming is now completed.
6. Insulate (tape) the WHITE wire.
System Test
Make sure the gear shift is in park, the hood is closed and the emergency brake is on.
Press button 2 on the alarm’s remote control. The parking lights will flash twice and the engine will start.
Press the brake pedal. The engine will shut down.
Repeat steps 1 & 2.
Open the hood. The engine should turn off. Close the hood.
Repeat steps 1 & 2.
Insert the key into the ignition and try to crank the engine. The starter should not grind. Push the brake pedal and turn
the ignition key off.
8. Repeat steps 1 & 2.
9. Leave the engine running. It should turn itself off after 20 minutes.
