I have a 93 max with the bose. The previous owner had sony ****ty HU w cassette with the wiring all crimped to the stock harness/amps but AM speakers crimped to the amps, but some ******* broke in and stole the faceplace of that POS. So now i put in a new one and i cant get the wiring to work. It seems like i got the right wires, but only when nothing is connected, and i hit 2 wires together, it sets some relay off and it clicks the speakers. From there i can get sound out of the speaker. If i hit touch 2 wires together on accident, it somehow sounds like it disconnect the relay and NOTHING works. Only if i disconnect all wiring and start over, will it work.

What am i missing here. I know this works cuz he had the previous HU hooked up. Ive never done a stereo install before so dont flame me if im missing something
