Car Stereos: 1990 Chevy truck radio, radio controller, chevy truck

Question
Thank's for the answer on how to connect my radio controller to the receiver, it was helpful. I just have one more question for you. The controller has two connectors, one with two wires, yellow and white and the other has several wires which is the controller connection to the receiver. What is the two wire connector for?

Answer
Ronald,

It's been a while since I've worked on one of these trucks, so my memory is a bit fuzzy.  I do recall the 2-wire connector you're talking about, and if memory serves, it's usually plugged into a similar wire harness coming directly from the cassette player.  If your truck doesn't have a cassette player, then it's likely that the 2-wire plug doesn't need to be connected to anything.
