Hello, all:

Not much of an electrical whiz but am willing to try. I have an original 86 GT Premium stereo with cassette that I think works, including the tape. I'd like to test it before trying to install it. The one in the car has tape issues.

What's the best way to test this unit meaning how do I apply power without frying the thing? I checked the wiring diagrams and the EVTM but they seem to only show three wires whereas this radio has four wires in the power connector. Need to make sure its grounded too.

I suppose I could just unplug the harness in the car and connect it but a bench might be easier.

Thanks for the advice.

M
