Electrical pinouts? Electrical system manuals?
 

Im working on my 88 10th anniv turbo 2 and i need an electrical troubleshooting guide.......



Im trying to rewire all of the factory ignition switch, headlight switch, and accessory wiring into a switch panel so i can loose the dash and am doing a little more work than i would if i had some sort of guide of whats what.



In laymans terms I basically i need to know what each wire does, its color, and where it comes and goes thats running to the stock headlight switch, and ignition switch so i can cut the stock stuff off and run its wiring to my toggles and momentaries instead.



Thanks for any help!

Do a search in the FC forum for the Factory Service Manuals (FSM). The PDFs are available online and IIRC the S4 ones have the wiring diagrams included.
