There is a plug mounted on side of the radio with a light blue wire. What is this plug for?

I think that is the rear speaker lead (blue) wire.

It's to power the reverb unit. It goes to the harness with the dash mounted reverb switch.

Interesting that the wiring for the AM/FM vs the AM is not the same. I've looked at the radio diagrams in the Delco radio manuals but never noticed that before.

All times are GMT -4. The time now is 03:48 AM.
