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?

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.
