Dave -

Yellow/black is 12V ignition-switched power.

Black is ground. NOTE: That wire grounds everything from the firewall to the rear of the car, through the second pigtail exiting the center cavity in the connector with a ring terminal that screws to the bottom of the lower instrument panel brace just to the left of the radio.

Gray is the radio dial light.
