I picked up a 1989 radio and wanted to swap it out with my 1985 bronco radio with the "*****." Does anyone know the correct wiring set up for this swap. The connectors are dramatically different. Stock harnesses, "coming out of radio" have 3 wires on one, blue/red, orange/purple dots, yellow/brown dots, and 5 coming out of the other for the speakers.......I believe the single black wire on this harness is a common ground because there is no balance or fade o for the 4 speakers in the bronco.... is that right about the common??? Where as the newer radio has 5 coming out of the one harness, Green/yellow, blue/red, RED, black/yellow, orange/black, the second I know is all speaker wires. Is there an easy way to connect these up???? I know thats confusing but I can show pictures if you think you can help. I wish I knew how to post pictures.
If you get the colors figured out, and you don't want to cut your original plugs off your harness, here's what I did on another vehicle. Go to the auto parts store and get one of those aftermarket harness plug kits for your 85. Then go to the junk yard and cut the harness for the newer radio out of a car or truck that will plug into your 89 radio. Then you can splice the wires together without butchering your 85 harness.
