Glad you got the preset issue fixed.

He said it was a decent radio that wouldn't keep the presets. I took that as meaning an aftermarket radio of decent quality. The stock radio wouldn't have had electronic presets. I don't think the digital Delco was available yet in '84 and it appears to be a low-option Burb anyway.


Yeah, that's exactly what I thought he meant too. Otherwise he wouldn't even need a constant power supply.

Hey Bucket i used the orange wire under the dash to yellow wire on the radio it worked my presets all worked . One more thing done . Thank You .

One other thing i noticed behind the ash tray there is a thicker yellow wire thats been cut and there is thicker black wire that has also been cut by the way its has been cut its obviously they where connected what would that be ???


Those are most likely the wires to the factory radio (YEL is the power and the BLK is the ground). There should be a gray wire with them or somewhere nearby. That would have been for the radio's backlighting - from the instrument lighting circuit.

Hey, if you run across a black wire with a yellow tracer between the ashtray and guage bezel it is NOT a ground.

In one of my jackass moments, I could not for the life of me get any continuity out of it with my meter no matter how many times I probed that damn thing. Eventually, I realized it was a piece of fiber optic to send light to the lighter. Live and learn.

DOH! Good to know, though.
