I searched and couldnt find a diagram for the engine harness. I need one that says what each clip on the harness goes to. Thanks

where is the wiring diagram in that faq

 

Third question down:

I don't want to buy a shop manual for my car, is there a place where I can still find out the information from one
Shop manuals for both series can be found on-line at:
http://www.cochran-racing.com/FSM/index.html
http://slackerware.dynu.com/fsm/
http://208.62.166.66:82/guest/shop_manuals/
or (86-88)
http://www.teamfc3s.org/main/factory...ual/1986_1988/
and (89-91)
http://www.teamfc3s.org/main/factory...ual/1989_1991/

 

I looked at the fsm and in the engine electrical section and couldnt find a main harness diagram.

 

no offense but you aren't looking for a wiring diagram
a diagram won't help you
you're looking for a list that some guy wrote up while pulling the harness off his car.
what do you need to know this for anyways?

 

S4 or S5???

The S4 manuals posted have every single wire and connector in the car.

The S5 manuals you would need to look in the appropriate section (such as engine emissions for the ECU wiring, or Engine electrical for the alt and starter wiring).

 

I am modifying my s5 harness to work on a 13b re motor so I need to know which clip on the s5 harness is for injectors, and so on for all the parts I need to connect.

I just need a diagram that shows what each clip is.

 

You would have to go by wire color. Not even the wiring diagram will have what plug is for which injector on a S5 harness. It will only have what wire color is for what injector.
