Introduction:

This integrated chassis/fuel injection harness can be used to wire any vehicle with an

LS1/LS6 engine, 4L60E/4L80E/4L85E transmission and a chassis that utilizes switches, lighting and other circuits that are 12Volt and negative grounded. Fuel injection wires are color coded as a 2000 to 2002 Camaro Z-28. Chassis wires are color coded as any

1970s to 1980s General Motors vehicle would be. With this harness fitting such a wide range of vehicles, these instructions should be considered general installation procedures. Referring to a factory chassis wiring schematic of your vehicle will aid in connecting to factory switches, lighting and accessory equipment. Most manuals sold at auto parts chain stores provide a basic wire diagram. Please do not attempt to modify this Painless harness to function as your factory harness did. We have developed this harness to function as this manual instructs you to connect it.

We suggest you make identification labels and apply them as you remove the old harness from your vehicle. Marking the sections, connectors and single wire connections during the removal gives you a great backup resource to use if you forget which wire goes where while installing this Painless harness.

Be sure to retain any wiring pertaining to the following accessories as this Painless harness only provides fused power circuits for these:

•

A/C-Heater selector switch, blower motor resistor and blower motor

•

Power window motors, switches and relays

•

Power door locks, switches and relays

Contents of this Painless wire harness kit:

Refer to the contents figure on the front page to take inventory. See that you have everything you’re intended to have in this kit. If you find that anything is missing or damaged, please contact the dealer where you obtained the kit or Painless

Performance at (800) 423-9696.

This Painless Wire Harness Kit should contain the following:

•

Wire harness

•

2 large parts bags containing heat shrink, 4 inch zip ties, 7 inch zip ties, umbrella zip ties, rubber alternator wire boot, rubber grommets GM turn signal switch connectors, GM ignition switch connectors, GM headlight switch and dimmer switch connectors and four H4 headlight connectors.

•

1 bag labeled, PP-720, this is a pigtail for the input speed sensor found on

4l80e/85e transmissions.

•

1 clear plastic, bubble pack, parts box containing miscellaneous ring terminals, spade terminals and several types of Packard terminals.

Things to know about the Delphi Powertrain Control Module (PCM) utilized with this Painless harness:

•

The GM service #12200411 PCM was factory installed in many different makes and models of General Motors vehicles. Both V6 and V8 engines can be operated by this controller. When procuring a PCM for use with this harness be sure to specify it be from a 1999-2002 Camaro Z28 or Trans Am.

3

•

The factory Camaro Z28 and Trans Am calibration incorporates a Vehicle Antitheft System (VATS). VATS must be turned off or otherwise the engine will continuously start for two seconds and then die, when cranked.

•

Factory installed emission devices include: fuel tank pressure sensor, tank vent solenoid, tank purge solenoid, air pump, air pump solenoid, and exhaust gas recirculation solenoid. The calibration installed at the GM factory onto your PCM tells it to look for all of these emissions components. This Painless harness does not include any supporting wiring or connectors for these.

•

The final drive ratio utilized in 1999-2002 Camaro Z-28 and Trans Am cars was

3.23:1. The rear tire on these vehicles had an overall diameter of 25 inches.

Transmission shift schedule calibrations are based around this rear end gear ratio and tire diameter. Most likely your rear end gear ratio and tire diameter is different than this. If so, without a calibration change to the transmission shift schedules your vehicle may up shift late/soon and down shift late/soon. You may also experience improper torque converter lock up operation.

•

This Painless harness utilizes two cooling fan relays built into the fuse block.

Both relays are controlled by the PCM. Fan 1 relay factory calibrations are 226 o F on and 219 o F off. Fan 2 relay factory calibrations are 234 o F on and 227 o F off.

LS1/LS6 engines were factory installed with a coolant thermostat that opens at

195 o F. Aftermarket thermostats are available with a lower opening temperature.

If you plan to use an aftermarket thermostat you must have both fan relay on/off temperature calibrations changed. We suggest an on temperature of 215 o F and off at 200 o F for fan 1 and 2.

Non-electrical parts and other things you should consider when transplanting an LS1/LS6 engine and 4L60E transmission include:

•

If your engine has not ran for several months or more you will probably experience the joy of clogged injectors when you go to fire it up for the first time.

Do yourself a favor and have the injectors cleaned, or purchase new fuel injectors. If you do not, your engine will probably not start due to clogged fuel injectors.

LS1/LS6 engines all came equipped with Delphi EV1 injectors. Different part numbers have different lb/hr rated injectors. 12533952, 12482704, 12561462 are rated 28.6lb/hr @ 58psi. 12456154, 12555894 are rated 26.2lb/hr @ 58psi.

•

Fuel system requirements include a high pressure, 56-60 PSI, fuel pump. The fuel feed line to fuel rail must be at least 6AN or 3/8” in size for stock engine,

350450HP, setups. If your engine’s output is more than 450HP you should use -

8AN or ½” fuel rail feed line. Walbro manufactures a wide variety of high pressure fuel pumps and installation kits.

If your vehicle’s fuel tank is one with the early small 1 & 13/16” hole sending unit you have several options of how to upgrade it. One option is to modify the

4

sending unit yourself by adding a fuel return line. Another option is to replace the sending unit with an aftermarket one from a company such as www.robbmcperformance.com

. They offer drop in units with a variety of tube sizes and adapter fittings. The other option is to have a company such as www.rockvalleyantiqueautoparts.com

cut out the old flange and weld in a large flange from a later model 1984 & up GM vehicle. The larger flange will allow for an in tank mounted fuel pump.

LS1/LS6 engines have dead headed fuel rails. They require 58 pounds of fuel pressure. GF-822 is a Delco return type fuel filter/regulator that can be plumbed in between the fuel pump and fuel rail. It will filter the fuel and maintain 58 PSI at the fuel rail. Another option is to mount an external bypass regulator such as one from Aeromotive. Just be sure to purchase a regulator that can handle 58 PSI and the amount of fuel volume that you need.

•

LS1/LS6 engine cooling systems have some specific requirements. First, the lower radiator hose connects to the water neck with the thermostat behind it. If looking at the front of the engine it is the water neck to the lower left of the water pump. The upper radiator hose connects to the water neck at the top of the water pump. Second, the factory coolant thermostat only starts to open at 195 o F and is fully open at 210 o F. Aftermarket thermostats are available that will open at a lower temperature. Third, these engines incorporate steam tubes that are plumbed into both the front and rear of each head. They are all tied together and then plumbed through the bottom of the throttle body and then to the radiator.

Most people remove the throttle body from this coolant loop by connecting the steam tube outlet, which is located just the lower right of the throttle body and protruding forward from under the intake manifold, directly to the upper radiator hose or to an open coolant bung in the radiator. Do not plug off this steam tube, it must be connected to either the upper radiator hose or to the upper third of the radiator in order to bleed off any steam that accumulates in the engine heads.

Companies such as Afco www.afabcorp.com

manufacture direct bolt in radiators that are specifically designed for LS1/LS6 engine transplants. These are ideal especially since the coolant inlet and outlet are both on the passenger side of the radiator. By moving the upper radiator inlet to the passenger side the driver side is opened up to allow a fresh air intake elbow to be routed there.

•

Coolant temperature and oil pressure gauge senders can easily be connected to any LS1/LS6 engine. In both engine heads are threaded coolant ports with

Metric 12 x 1.5 threads. The coolant port on the driver side head is utilized by the coolant temperature sensor needed for the PCM. The port on the passenger head usually has a plug in it that can be removed and a temperature sender for a gauge can be inserted. Most aftermarket gauge manufacturers offer adapters to adapt their gauge sender so you can thread it into this coolant port.

There are two places that oil pressure senders may be connected to these engines. Behind the intake manifold is a threaded port, Metric 16 x 1.5 threads.

Depending on what vehicle your engine was donated from, this port might already have a 0-5 Volt oil pressure sensor in it. This Painless harness does not have connections for this sensor so you may remove it and with an adapter screw in your oil pressure gauge sender. Another spot that is common for oil

5

pressure senders is just above the oil filter. Here you will find an aluminum cap with two hex head, 8mm bolts holding it to the oil pan. You can remove this cap, tap it to the threads that match your oil pressure sender and then reinstall it. Just keep in mind that if you plan to use headers this location for a sender may not be ideal. Heat can kill a sender quick.

•

4L60E, 4L80E, & 4L85E transmissions require external fluid coolers. The ports on the side of the transmission usually have quick-connect fittings installed. Most local auto parts suppliers will offer fittings that adapt these ports to pipe flare fittings. If you plan to bend your own hard lines this is your best bet. Or, you can also screw in 3/8” NPT fittings into these ports. Make sure to use Teflon tape on the threads for a good seal. Fittings are available from many online retailers or your local hydraulic hose shop that are male 3/8” NPT to male -6AN or whatever your application may need.

Shifter detents are another thing to consider when transplanting a modern automatic transmission into a vehicle that was originally manufactured with a 2 or

3 speed transmission. Companies such as Shiftworks www.shiftworks.com

manufacture shifter conversion kits to upgrade your factory shifter to operate your late model transmission. Another option is to completely replace the shifter with an aftermarket one such as Lokar www.lokar.com

part # FMS64L60EEM.

•

Throttle cables originally installed to your transplant vehicle may or may not be long enough to reach the LS1/LS6 throttle body. If it is not long enough or just doesn’t seem to work properly because it is worn out/frayed then check out Lokar and their universal LS series throttle cables. These are cut to fit and easy to install.

•

Engine accessory and frame clearance always seems to be an issue that comes up when transplanting a LS1/LS6 engine into any early model vehicle. Usually the alternator and power steering pumps do not have any clearance issues associated with them. The factory LS1/LS6 A/C compressor mounts to the passenger lower side of the engine. In this location, it will not clear most GM frames. You will either have to notch the frame to create clearance or move the

A/C compressor. Companies such as KWIK Performance www.kwikperf.com

offer relocation brackets that move the compressor to the upper passenger side of the engine. Moving the compressor to this location works well with most transplants. These kits utilize a Sanden style compressor.

•

Drive shaft length will have to be modified if you are upgrading to a 4L60E from most 2 & 3 speed automatics or manuals. You should also consider having the entire tube upgraded to a thicker wall material since you are likely to exceed the handling capabilities of the original tube.

Tools Needed:

In addition to regular hand tools such as ratchets, sockets, extensions, screw drivers, flash light or drop light, you will need the following tools:

Wire Crimping and Stripping Tools:

Two types of crimping tools are needed to install this harness. Painless Performance

Products offers part #70900 for crimping non insulated “factory” style terminals, these crimpers can be seen in the photo below. You will need this style of crimper to crimp the terminals used with GM turn signal, ignition, headlight and dimmer switches.

The second style of hand crimper shown below can be purchased from just about any local electrical supply shop, home improvement store or can also be purchased online.

You will need this style of crimper to crimp the heat shrinkable, insulated terminals included in the small parts bubble pack.

A good set of wire strippers are required to strip wire properly. Shown below are a pair of strippers manufactured by Klein tools and that are available from just about any local electrical supply shop, home improvement store or can be purchase online. This style of wire stripper is ideal for this harness install because of its ability to properly strip wire gauges 10awg to 20awg.

7

Volt/Ohm Meter:

A Volt/Ohm meter is always a good tool to have on hand when installing any type of electrical components into any vehicle. Most basic units provide the two functions required to diagnose most electrical issues seen during a harness install. These two functions are the ability to read DC Voltage and electrical continuity or Ohms. They can be purchased from any home improvement store, local hardware store and electrical supply shop and online.

Battery Charger:

A battery charger is a very useful tool to have when initially connecting power up to a newly installed wire harness. Battery chargers are available from any auto parts, sporting, home improvement or local electrical supply store. Be sure the charger you purchase has a low (5-10 Amps) setting.

*NOTE: The PP-720 pigtail supplied with this kit must be added to the harness in order to utilize a 4L80e/85e transmission. Additionally, the transmission connector must also have two wires re-pinned and the ECM must be flashed for the correct transmission . Instructions for these modifications can be found on the next page. These modifications are easier to make before the harness has been installed.

10

4L80e/85e Transmission

* Note : A custom ECM tune will be needed in order to run ECM flashed with a

LS1 operating system as these engines were never factory equipped with a

4L80e/85e transmission . The 60608 harness has the transmission connector pre terminated to allow use of a 4L60E transmission. In applications where a 4L80/85e is to be used, follow this procedure to change your transmission connector to ensure all functions of the transmission work properly. See the diagram below for repining the transmission connector. The supplied input speed sensor pigtail, labeled

PP-720, will also need to be added to the ECM/ harness.

Transmission connector Re-Pin

1. With the terminal end of the connector and the arrow on top pointing towards you, carefully remove the white retaining lock located in the center of the connector.

2.

Locate the white wire located in terminal location S. Using a paper clip or small screwdriver, gently lift the locking tab inside the connector and pull the wire from its location. The white wire has no function with the 4L80E transmission; it needs to be taped up and stowed in the harness in case a

4L60E is ever to be used.

3.

Now locate the brown wire located in terminal location U. Using the same method, remove the brown wire from it’s location

4.

Gently insert the brown wire into terminal location S.

Transmission Connector Pin Out

Adding the Input Speed Sensor Connection, PP-720

Wires from the pigtail have been pre-terminated and have had the appropriate connector pre-installed. You, the installer, must simply install the 2 terminals into the ECM connector and route the connector to the transmission section of this harness. It needs to match the length of the VSS connector from the harness. Extra length has been supplied to fit those with extra-long Painless EFI harnesses as this pigtail is also used in other Painless harnesses. In most situations this pigtail will have excess length that will need to be coiled up or cut off. Extra ECM terminals have been supplied in the event the installer wants to cut the pigtail to length. Rollover crimpers, like Painless part #70900 will be needed to crimp these terminals.

4.

Locate the RED ECM connector. Looking at the wire insertion side of the connector, identify pin locations #22 and #23. These locations will be empty.

Using a small screw driver, press the locking tang on one side of the terminal lock and pull the lock away from the connector. Once one side is done, do the other side as well to completely remove the lock from the connector.

You only need to remove the lock from side of the connector with pins 22 and 23.

Locate the Input Speed Sensor pigtail supplied with this kit. This pigtail will have a RED/BLACK and BLUE/WHITE wires. Plug the RED/BLACK wire into pin #22 and the

BLUE/WHITE wire into pin #23. Re-install the RED terminal lock.

Route the pigtail with the other transmission wires to the transmission and connect it to the Input speed sensor, located towards the front of the transmission. Please be aware that this connector is also the same connector that plug into the VSS sensor, do not mistakenly plug the Input Speed sensor into the VSS on the rear of the transmission and or the VSS connector into the Input

Speed Sensor.

Mounting the fuse block:

The 26 fuse 7 relay fuse block is the center point of this integrated harness. All power is routed through this fuse block. The first step to installing this integrated harness is to mount the fuse block. Remove the front cover from the fuse block.

•

If looking at the front of the fuse block you will see a mounting hole on the lower right side. Use a bolt and this hole to secure this fuse block if possible.

•

Another option for mounting this fuse block will require you to remove the rear cover from it. Insert a small, flat screw driver into the red slots as labeled in the picture below. Push the screw driver about ½” into the slot, gently pry on the screw driver handle towards the center of the fuse block while at the same time pulling the rear cover away from the fuse block. Do this for all four release slots.

Once the rear cover is released from the main body of the fuse block you may notice the need to cut the tie wraps around the wires protruding from it in order to completely remove it. If so, cut the tie wraps and completely remove the rear cover from the fuse block. The front cover and rear cover will click together without the fuse block in between them. Just line them up and push them together until you hear the two locks click. You now have an accurate mock up of the fuse block to aid you when figuring out where to mount it. You can now make a custom bracket or just run some self tapping screws through it to hold this rear cover in its mounting place. Be sure any mounting solution you use does not distort the rear cover or introduce any sharp metal objects that could short out wires when you reassemble the fuse block.

13

Mounting the Powertrain Control Module:

The Delphi PCM utilized with this harness must be securely mounted away from excessive heat, water or oil and road debris. We provide 5 feet (1.5 meters) of harness between the main harness body and the PCM connectors. The harness also provides 3 feet (1 meter) of harness between the PCM harness breakout and the fuse block. So, finding a spot to mount the PCM should not be a problem. Custom mounting brackets will be required.

•

Behind the dash board is always a good place to mount the PCM. Depending on your dash board and whether or not your a/c evaporator box will allow for it, you most likely can mount the PCM here.

•

Under the passenger seat is another good place to mount the PCM. The 5ft of harness should allow you to mount the PCM here. Just be sure the seat has enough clearance below it to not crush, scrape or damage the PCM or harness.

•

On some vehicles, behind the passenger kick panel, there is a cubby hole large enough to mount the PCM. If your vehicle has this cubby hole feel free to mount the PCM there.

•

Engine compartments usually have ample room that can be used for PCM mount places. For instance, many vehicles have large cubby holes between the inner fender, out fender and firewall. Sometimes this area is used for a/c evaporators and blower motor mounting; so make sure the space does not already have a planned occupation.

14

Harness routing and attachment:

Now that the fuse block and PCM are mounted you can move on to routing the harness sections to their respective automobile locales. Take your time, leave enough slack in the harness to accommodate body/engine/chassis movement and keep the harness away from moving and/or hot parts. This complete wiring system, as well as this instruction manual, has been designed with five major groups incorporated into it.

These groups are as follows.

Engine section:

This sections wires are to be routed out the center of the firewall, into the engine compartment, and then to their respective component.

Includes wires and/or connectors that connect to the following: injectors, coils, engine coolant temperature sensor, alternator, throttle position sensor, idle air control, cam position sensor, manifold absolute pressure sensor, knock sensors, intake air temperature sensor, mass air flow sensor, crank position sensor, vehicle speed sensor, transmission solenoid pack, transmission mounted PRNDL switch, driver and passenger pre-catalytic converter oxygen sensors, starter, a/c compressor, oil pressure gauge sending unit, coolant temperature gauge sender and two engine grounds.

Dash section:

Includes fuse block, turn and hazard flashers, a horn relay, an interior ground connection, and the appropriate wires to connect the following: a/c-heater switch, wiper switch, ignition switch, headlight switch, turn signal switch, dimmer switch, cruise control switch, radio, gauge cluster, cigar lighter, courtesy lights, OBD-2 diagnostic port w/check engine light, driver and passenger power window/lock.

PCM section:

This section is to be routed to the powertrain control module.

Includes blue and red, 80 pin connectors for the powertrain control module.

Headlight section:

This section is to be routed out the driver side of the firewall, into the engine compartment, and then to their respective components.

Includes wires and/or connectors that connect to the following: high and low beam headlights, turn lights, park lights, grounds, brake switch, cooling fan 1 & 2, wiper motor, cruise control module and horn.

Tail section:

This section is to be routed to the rear of the vehicle. You can either route this section out into the engine compartment and then to the rear of the vehicle or route it under the door sill plate and then to the rear of the vehicle.

This section includes wires that connect to the following: fuel sending unit, electric fuel pump power wire, reverse lights, left turn/brake/tails, license plate light, right turn/brake/tail lights, grounds, amplifier activation wire and electric antenna activation wire.

15

Engine section:

To route the fuel injection engine section of this harness out into the engine compartment you will be required to drill a 1 5/8 ” (41mm) hole in the firewall. Be sure to deburr the hole with a round file and to fold some duct or electricians’ tape around the metal edge of the hole so as to not chafe the harness while inserting it. The harness allows 4 feet (1.2 meters) of length between the fuse block and first major fuel injection engine section break out. Make sure you measure where the hole should go according to the harness break out.

When pushing a fuel injection harness through the firewall always start with the largest connector. In this case the largest connector is the transmission solenoid connector.

After this connector is through the hole in the fire wall proceed to push all the other connectors through. This process is always easier said than done and we suggest you have a second person present to assist you with this. See photo below.

Once you have the entire fuel injection engine section through the fire wall hole begin to sort and route the harness to it respective component. Notice that the harness is broke out into several sections. Read each printed tag on the fuel injection section of the harness and connect them to their respective component. All connectors are designed with a key slot or pin configuration which requires directional insertion into its mating component. Do not force the connector insertion as this will break it, its mating component or bend the pins inside of either one. Route and connect the connectors to their mating components as shown in the next few pages.

16

Lay the fuel injection harness out onto the engine and decide how to secure it before making any connections:

1. Lay the driver side injector/coil break out onto the driver side fuel rail.

2. Lay the passenger side injector/coil break out onto the passenger fuel rail.

3. Feed the crank position sensor (CKP) connector and starter wires down to the starter.

4. Feed the passenger oxygen sensor connector down to where its sensor will be located.

5. Feed the transmission solenoid, vehicle speed sensor and park/neutral switch connectors down towards the transmission.

6. Feed the driver oxygen sensor connector down to where its sensor will be located.

7. Lay the intake air temp (IAT) and the mass air flow (MAF) connectors out to the where the sensors will be mounted. Use some of the included tie wraps to secure these wires to which ever injector bank you route it with.

Attach or connect the connectors and open ended wires for the engine and transmission to their mating components.

1. Locate the two black/white engine ground wires (labeled Ground #1 and Ground

#2 ) which protrude from the main engine harness breakout near the back of the intake manifold. These two ground wires need to be terminated using two of the large yellow ring terminals from the parts bubble pack. You must separate these grounds; bolt one to each engine head.

See the diagram below for more information on what these grounds are used for.

17

2. Plug the black, three pin, cam position sensor connector (labeled CMP ) into the cam position sensor located in the engine block at the back of the intake manifold.

3. Plug the black, two pin, knock sensor connector (labeled KNOCK ) into the knock sensor pigtail which protrudes from underneath the rear of the intake manifold.

18

4. Plug the grey, three pin, manifold absolute pressure sensor connector (labeled

MAP ) into the MAP sensor located at the center rear of the intake manifold.

5. Plug the 4, black, two pin, driver side, injector connectors into their mating injector. #1 cylinder is at the front driver side of the engine.

19

6. Plug the white, seven pin, driver side coil connector (labeled DRVR COILS ) into the mating coil harness located on the driver side valve cover.

7. Plug the black, two pin, engine coolant temperature sensor connector (labeled

ECT ) into the coolant temp sensor located just in front of the #1 cylinder exhaust port on the driver side head.

7. Accessory Switch Section

:

The accessory switch section of this harness provides wires for a cigarette lighter, a/c-heater switch, wiper switch, illumination power and ground. Connect the wires as listed. If your vehicle has an illuminated a/c-heat switch, wiper switch and cigarette lighter use the #969 & #930 wires to power the lighted sockets. a. Connect the wires for your a/c-heater switch as the diagram indicates. #904 wire is fused by the a/c-heat 30 Amp fuse. It provides ignition switched power for your a/c-heater switch. #902 wire is to be connected to your a/c request wire from your a/c-heat switch. If using the OEM switch it is the wire that originally went out to the a/c compressor clutch. When you turn your a/c switch to a/c or defrost this wire tells the PCM that you are requesting the a/c compressor to turn on. If the PCM sees this request as acceptable it then activates the a/c relay on the fuse block. This relay switches 12 Volts to the a/c compressor clutch which engages it.

39

Note:

Using the PCM to control your a/c compressor brings with it several benefits.

The first is the PCM has a built in rpm window that it allows the a/c compressor to operate within. Anything above 4300 rpm the PCM shuts off the a/c compressor. Once the engine rpm returns to below 3900 rpm the a/c compressor is reengaged. Second, the PCM shuts off the a/c compressor if it registers wide open throttle. Once the throttle returns back to 0% the a/c compressor is reengaged. The fans are shut off when the vehicle is travelling above 40mph. Finally, the PCM automatically activates the engine cooling fans when it activates the a/c compressor. b. Connect the cigarette lighter power wire #903 to your cigarette lighter or power port. Most of the time this connection will utilize one of the heat shrinkable bullet connectors from the bubble pack. If you are mounting the cigarette lighter into a non-metallic (non conducting material) be sure to add a ground wire to the bezel. The #903 wire is battery hot 12 Volts. c. Connect the #978, #979 & #976 wires to your wiper switch. Most wiper switches are self grounding into whatever they mount in. If your wiper switch is not self grounding you are required to add another wire to ground the switch. #978 wire is for the low speed of your wiper motor. #979 wire is for the high speed of your wiper motor. #976 wire is for the washer motor. If you find that your wiper system is completely different or you are having issues figuring out how your switch connects, please call our tech line @ 1-800-423-

9696.
