I know there are plenty of postings on this already, however my Nephews 1990 SC had all of the wiring cut at the dash when we got it. I have cut the the harness out of the 94 parts car that I have and am trying to match up the 94 harness wires with the 90 dash wires. I know the grounds are different and have the memory power wire and switch 12v wires hooked up. the radio comes on and nothing from the speakers. except if I put 12v to the heavy blue wire that comes from the dash then I get a humming from all speakers. The amp and sub are hooked up. The CD is not currently working bu I have an orange and light blue wire that is hooked to the wiring harness that send 12v when the radio is turned on but I have no display on that and it will not accept CD's
Last question . there is a small plug that has two wires and from the 35th anniversary site it looks like a remote on and return of some sort. I dont have the plug for that either is that hoookup necessary?
the good thing : those grey cables for the cd in and speaker outs are in tact,
thanks again, I would really like to find a 94 wiring diagram for the stereo.
thanks for your help this far, seems like a lot of folks have had troubles with the radio.
