Under the dash there are (3) 3 prong molds (yellow,orange & red) that you can plug a male terminal in.
Does anyone know what each one's purpose is ?

They are accessory power taps, as I recall, yellow is ignition/acc switched, red-unswitched, and orange being the dash illumination circuit.

Yellow with tan wire is accesories source.

Red with pink wire is constant battery power source.

Both are fuse protected on fuse box.

Orange with orange wire is cluster dimmer source. Does have two fuses ( at least on B bodies ), one whet feeds the INPUT to lights switch and one that is OUTPUT from dimmer function, coming from same input


THERE IS ANOTHER ONE AROUND!!! Black with yellow wire. Is door jam switch ground

thanks
