no sound from alpine head unit
i just sold my 91 fleetwood hearse ,so i took the deck i put in around december and hooked it up to my new 1994 caprice wagon (hearse ). everything comes on, but no sound comes out . the factory delco unit works fine and i hooked it up again to check . i put the alpine back in my 91 and it worked fine in it. i checked the 16 pin quick connect to gm post 88 harness,it said it would work on a 91 cadillac and 94 chevy . i looked inside the factory has 15 wires but the adaptor only has 12 . i cant find any other harness and i diont want to make a difference harness . is there more than one quick connect harness ? or is something else afoot with the audio gremlins ?
