Did Dodge change the factory radio wiring config for the power and speaker connectors from 1997 to 1998?
The connectors look the same (one gray, one black) and they fit together the same way but when I plug my aftermarket JVC head unit from my 97 into my 98 it does not work. It was working perfectly in my 97.
I also hear a sound like a relay clicking when I connect the JVC into the harness of my 98.
Both 1997 and 1998 wiring colors are:
Constant - 12V+ Pink
Switched - 12V+ Red/White
Ground - Black
Illumination - Black/Yellow
Left Front - (+) Dark Green
Left Front - (-) Brown/Red
Right Front - (+) Purple
Right Front - (-) Blue/Red
Left Rear - (+) Brown/Yellow
Left Rear - (-) Brown/Light Blue
Right Rear - (+) Blue/White
Right Rear - (-) Blue/Orange
Well then, I don't know what the heck happened. Possibly the different speaker configuration between the 97 Mark III and the 98 Cargo is causing trouble. I'll have to check it out wire by wire. Thanks for the diagram Alloro.
And I was expecting it to just plug in and work -- arghhh!
