Anybody figured out the wiring to use the OEM antenna with an aftermarket head unit? I'm getting ready to put the stereo in the 88 and would like the antenna to function with it.

It is gone once the car warms up but this is what I have isolated as happening. I start the car it idles low and drops then picks up to 1200 rpm where it should be. If I put the car into neutral and coast backwards with the parking brake off the idle drops and it acts like it wants to stall. Once I stop the car from rolling the idle goes back up. Once warm everything is normal. I have an idea of what I think may be happening but would like some ideas from the knowledgeable Starquesters here.   T
