Default 76 stock stereo wiring help

I'm putting an aftermarket stereo in my 76, the stock harness has three wires, can you tell me what the three wires are for and which is which? Thank you

Grey = +12V for the dial lighting. Comes from the Instrument Panel Lighting circuit--unlikely to be needed for an aftermarket stereo.

Black = -12V ground

Yellow = +12V from the radio fuse (10A)

Since most aftermarket stereos need a constant source of power, your best bet for such is to get it from the accessory circuit. Look for the orange wire feeding the lighter. Any part of that circuit is OK for a very small amount of power like needed for the memory functions of a modern stereo.

I am pretty sure it is:

yellow = power
black = ground
gray = lights (turns on with headlight switch)
