Hello, I have been searching for about an hour and cannot find what I am looking for so I figured I would post. Basically I removed all my emissions stuff and would like to slim down the wire harness to complement it. My initial harness was completely shot so I picked up a good used one. Does anyone have a diagram showing exactly what can be removed? I also plan on removing the OMP wires as I am going to be running premix. Any help would be appreciated. I can’t wait to finally drive my car!

 

you may not want to remove the IAC/ISC and the precontrol/wastegate solenoids, depending on your setup

 

Thanks, I cant remove the whole rats nest, I am still running the stock twins so I believe I need 3 of the selinoids. The picture definatly helps though.

 

Can anyone help me out with the colors on the rats nest solenoids?
Orange is FPR
Yellow is EGR
Not sure on the rest. I am finally working on the car again and want to simplify this harness as much as possible.
Thanks!

 

I did mine by: Breaking the harness down. Label every connector. Pull out connectors 1 at a time, and used a small punch to remove the wire from the ECU plug. Take your time, and you'll come out ok.

As for the wire colors, I don't remember them, you might wanna grab a copy of the Electrical FSM to help out. That is unless someone has it in front of them.

 

1- Black(top) - Charge relief
2- Green - Double throttle control
3- White - Charge control
4- Brown - Turbo control
5- Yellow - EGR solenoid
6- Gray - Switching
7- Blue - Relief 1
8- Orange- FPR regulator control

i only ran the Charge relief, charge control, the 2 turbo control solenoids and manual boost controllers instead of the wastegate and precontrol solenoids. Also for my harness i didnt want to hack it all up so i just put resistors at each unused connector and called it a day.

 

retained the bracket at the bottom so i can still mount the solenoids up to the front where i can reach them without having to take the UIM off. hope it helps.

 

Awsome Thanks

 

dont know if u found this yet but here ya go, i followed this exactly with the exception of the purge control solenoid and the omp routing and wastegate and precontrol solenoid routing since i deleted all that.
