Wrong board, but while I,m here all I can tell you is to get a shop manual for the specific make and model car you need this info on. It will show you every thing you could ever want to know about the wiring harness.

Yeah, this might be the wrong board, but the big red wires are probably leads from your battery. The big purple one is probably to your starter solenoid.
