Symphony II+ Wiring **Someone please help.**

2007 A4. Bose. No Navigation.

Will someone please help me here. I've posted twice about this and really need some help before a 10+ hour drive.

I need to know what each color wire for the B harness is. I have a good diagram for what the pin holes in the back of the unit are but unsure which color wires are supposed to match them. This connector was unplugged when I bought the car and now when I plug my B connector in, it blows the fuse to my unit. That would tell me the wires aren't lined up with the right pin?

I'm really asking for some help here please.

Or more likely, that something is shorted to ground downstream of one of the wires. I'd do a continuity test between each pin and ground. You should get nothing on all wires except the grounds shown in Okeydokey's drawing. When you get continuity to ground, you'll know which wire is the problem.

On second thought, that looks like a drawing from an old Audi 4000. Try this one.
