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.
