Hello, I have a T / C of 1979 I do install new radio, the original connector has 3 wires one yellow, one gray, one black, and one which 12v, the yellow one? What is black? What is gray? And where the remote connection of the amplifier? ::) thanks guys ;)
-
12v is usually red, black is usually ground, im guessing grey and yellow are left/right speakers?
-
Yellow is power (12V)
Grey is illumination,
Black is ground.
Are you installing a factory radio, or aftermarket?
-
I install a Kenwood, I had the radio delco original but it feels good :-[. Thank you very much for information :)

If your wiring is not already butchered up, I highly recommend dropping a few bucks on a wire harnesses stereo adapter when installing an aftermarket radio like the Metra 70-1677-1, Scosche GM01B, or equivalent. This way you are not cutting up factory wiring.
