My 69 El Camino came without a radio. And a variety of wiring issues. I've had the dash apart for about a week now chasing electrical gremlins. As best I can tell my truck Never had a radio. But there is a dash mounted speaker.. The lack of a factory radio doesn't bother me much, I'll wire as I need to for an aftermarket stereo. My question is: My truck does not have an accessory position on the ignition switch. Is that even possible?
