need help finding ground for radio.

[Steven_Anderson]

I already read the radio wiring sticky and printed out the diagram but I cant find a ground wire thats the only one I cant find the PO ran new rear speaker wire but left the old wires in the loom at the deck.

I know it should be brown or brown with black but I have two brown with black and I think those are the old rear wires.

Here is a picture of the wires I have at the dash.

im sure someone on here can give you a more direct answer than me, but when all else fails i whip out the volt meter. :)

brown with black stripe. is ground, take you pic one which one. the one on the right looks like one for a ground for a switch light.

[Steven_Anderson]

tried both the brown wires and it didn't turn on.

[Cabriolet]

did you use an volt/ohm meter to make sure they are no cut by the PO and also you have the right positive lines?

Definitely good advice and you would also thing just good old common sense.
Trouble is this guy, like a lot out there, would not know what to do with a test light.

Why don't you just ground it to the metal cage that holds the headunit in place just sand it well and put the wire under a bolt

^ word. The stock e30 ground sucks anyways. I still have a/c hum and I cant figure out how to get rid of it. Any suggestions would be greatly appreciated.

Holy shit, I just noticed this.

Congrats on the promotion, a supermod at that.

What color should the 12v acc be? on the diagram it has it as purple and grey but I don't have a purple and grey wire. thinking that this is the problem.

What wire lights up your test light when you turn the key on?

Harbor Freight test light $3.99

Hell, solder some wires on a lightbulb for all I care, get a testlight!
