I received what appears to be the correct wiring harness for my 2002 with the BOSE system, and the same thing is happening - the stereo comes on, I can select stations, everything works but no sound. It appears that there is only one way to plug the harness in (with the large stock brown connector not being used). If I do indeed have it hooked up incorrectly, then I'm an idiot and someone here will point me in the right direction (and I'll own up to being an idiot, it's something I'm kind of used to). Or, the harness or stereo have a problem.

I have not yet dove into checking voltages from the pins yet.

Any ideas?

EDIT: I am an idiot. It turns out that you plug the stock brown connector into the stereo, and the brown connector on the new Bergvill harness is unused. Kind of non-intuitive if you ask me (which I'm an idiot, so why would you ask?).

Anyway, it all seems to work, and it sounds great and looks so much better than the aftermarket deck I had before.
