At long last, I have a radio! Finally broke down and bought an aftermarket radio and took the time to pull new wiring to all 4 speakers. I figured that way I could leave the original wiring harness intact if I ever returned to the OEM radio. Took about 4 hours yesterday evening, but worth the effort. New radio sounds good and as a delightful side benefit, the power antenna works! Talk about high-class, now I have working A/C AND a working radio!
