Default Radio Wires?

72 Corvette....original radio is long gone.

Which wires do I use to hook up a new radio?

I am assuming that:

Yellow = ignition switch on/off
Gray = constant power
Black = ground

The gray and black wires run together in a plug.

Pls comment.

The gray wire is for the dash lights and the radio lights. Power is on only when the lights are on. Yellow is power, black is ground.

You will have to source a continuous power for the radio memory, use the orange feeding the clock and cigarette lighter. Yellow is switched power so the radio turns off with the ignition.
