Since I've been unable to located the rest of the door harness's (parts not even listed in parts book) to make my McIntosh Stereo build complete, I'm going to try to fit an aftermarket radio in the car. The blue connector is McIntosh; the Gray connector is for base radio. I've been unable to locate a mating connector. No numbers on the connectors (very unusual) and I've tried Mouser, Digi-Key, Yazaki, Cutchfield, etc..... to find a mating connector to the gray one. Wondered if anyone has any suggestions?
