Guest Posted June 11, 2004 Share Posted June 11, 2004 Anyone that can help. I have a 76 Olds Cutlass Supreme and I am taking out the AM radio and installing the AM/FM factory radio but the wire harness is not the same. The AM is a smaller plug. Is there an adapter that the small plug can convert it into the bigger plug in that plugs into the back of the AM/FM radio. Any feedback would be appreciated. Maybe someone can tell me where to get this wiring harness adapter. Link to comment Share on other sites More sharing options...
rocketraider Posted June 12, 2004 Share Posted June 12, 2004 A good electronics or radio supply shop (probably NOT Radio Shack) should have an adapter plug that will work. You still may have to make up some jumper wires and run rear speaker wiring. I think AM cars had only the two dash speakers.I put an 80s Delco Digital AM-FM-cassette in the 76 98. To avoid cutting up the car wiring, I got the proper aftermarket adapter plug for the radio unit and then put small straight spade terminals on the plug wiring to adapt it to the car wiring.
