I have an 87 NA and i've stripped the interior and taken all the wiring out, im replacing the ecu with a standalone and stupid me forgot to figure out which wires coming out of the ignition switch are which. Im hoping someone can point me in the right direction to find out which are which. I downloaded the wiring diagram but it isnt clear at all. Any help is much appreciated!!!

According to the diagrams I'm pulling up on alldata...
black = power to switch
brown = start circuit (to S terminal)
black/white tracer = run circuit
I can't find a diagram showing the color of the remaining wire, but it looks like there should only be one more for the accessory circuit. let me know if I need to keep looking.

 

Works just like the free online manual shows. I put a red X over the four prong, useless, not worth talking about plug.

 

Thanks guys! Where is this online manual, i cant seen to find the one that you were using, it looks 10 times better than the wiring diagrams i have.

 

The ignition key is in ENGINE ELECTRICAL. Wiring is in...wiring diagrams.
