Ignition switch ground wire color?

[deutschman]

I can't figure out which wire from my ignition switch is my ground wire. I have my manual out and it shows me all the wires but some of them are different colors or just don't exsist. I have large wires that are red, black, violet, green, green/white. I have some small wires that are brown, brown/red, brown/green, brown/blue.
Any help?

PS
Yes this is an e30 ignition switch.

Dont know. I got the steering column off the forum here and I never asked. I got it all wired up and working though. Just took the better part of a day.

there isnt a "ground wire" in the switch

red is constant power in,
black is power out to the starter
the other 3 large wires are for other electronics like ecu, main relay, fuel pump ect
