well after working all freakin day to install my fm modulator, changer and tv tuner, which was torture, never worked on a car as difficult as this, the stuff doesnt work, i had some problems finding the wires i needed behind the radio so i used the light blue wire in the amp harness for a 12V+ ACC lead, i metered it and it was 12V+ with ignition. now my stuff wont even power up so i dont know it that isnt turning it on or if i pulled something loose while putting the dash back together. does anybody know what color the battery, ground, and 12V+ ACC is behind the radio/HVAC unit. any help appreciated

if nothing works and it was working before, make sure its properly grounded.

i dont really understand what you've done so I cant help you out.

The best thing to do would be to find someone with the service manual and send you the diagram with labels for the wires.
