I've been through the Bentley wiring diagrams, but I can't figure out what these three wires at the ignition switch connect to: brown, blue/white, and green/white. Car is a '92 e36 325is.

I'm rerouting these to a seperate panel of switches on my race car.

Thanks

Brown is ground....I know that much. :)

Use a test light...one should to be constant, the other the starter.

I should have known Brown IS ground - thanks. NE1 got an idea on the other two? I think one might be the on board computer.
