Anyone have a pic of the pigtails for the radio? Putting mine back together and I’m finding only 2, and I believe there are 3 that plug into the radio. Radio is working, no illumination for the dial.

Is one of the wires in the plugs a grey one?
That should be for the illumination.

First... Make sure the other dash lights are dimming with the headlight knob.

If they are working, it may be a burned out bulb inside the radio.

There are 3 plugs. They wire up like this.

Interesting info... A 79 Camaro never came with two front speakers
So, two of those slots in the middle plug (5-8) would be empty.

They only had two rear speakers with the U80 option.
Same deal on that plug (9-12)... Two empty slots on the speaker harness if it only had a single rear speaker.

If the radio powers up... You apparently have the plug with connections 1-4.
That plug should include a grey wire for illumination and brightness would be controlled by the rheostat in the headlight switch.

Here’s the Hayne’s manual schematic for a 79…
