here nigels writeup on the g60 harness
this harness is from a syncro passat but we used a Corrado bentley manual to figure out where everything goes. If you want a larger picture so you can read the labels better just ask and i will e-mail them to you.
To get the harness to this stage i soaked the harness in superclean and HOT water. this made the insulation more flexable and removes the tape and dirt much easier.
be carefull cutting the outer covering off
any way here is the wiring key moving in a clock wise manner from the bottom left
Fuel Rail-Brown/Yellow stripe, solid Red goes to #87 on the fuel pump relay
Red/Green strip- goes to #50 recieves +12v during starting
Terminal 1 on coil (negative -)- solid Green wire larger diameter, has a specific plug for the coil
*Heated O2 sensor- solid purple (signal), soild black (ground), brown with black stripe (ground), Red with white stripe recieves power from #87 on the fuel pump relay
AC- solid Green but small diameter wire with yellow plug (not to be confused with the coil negative) goes to a switch in the of the interior of car the lets the brain know to idle higher because of the increased drag of the AC compressor ( i will be deleting this from my harness but http://www.snstuning.com use it to activate some of the special features available on their custom chips)
Knock Sensor-i did not label it because if you cannot recognize which connector it is you should not be attempting this project in the first place
ISV or Idle Stabilizer Valve- Solid White/ Black with Yellow stripe recives power from #15 which is switched 12V +.
The ISV can be succesfully eliminated for those looking to reduce the complexity of the harness, it will idle alittle rough on cold days however the blk/ylw wire will still need to be powered
Air Temperature/CO potentiometer- Blue solid, Blue with White stripe, Brown with White stripe
Throttle Switches- Brown with White stripe, Red with Black stripe (idle switch), Blue with Black stripe (Full throttle switch or Wide Open Throttle or WOT switch)
Coolant Temperature Sensor- pretty blue plug, Brown with White stripe, Brown with Green stripe
Distributor Hall Sensor- Brown with White stripe, Green with White stripe, Red with black stripe
Yellow with Blue stripe, goes to #85 on fuel pump relay
Brown and Brown with black stripe are grounds.
*Note for those with passat harnesses- the black wire in the O2 sub harness is not grounded in the actual harness connection with the brain. But instead relies on a seperate ground in the engine bay. Corrado harnesses do groung this at the ecu connection plug. So don't use a corrado O2 sensor unless you go connect the ground at the head of the wire in the ecu connector plug.
