I've got a stock Pioneer radio/cd unit that I purchased but the plug on the unit was different than on the one I was replacing. I'd like to sell it but would like to test it first so that I know it works. I have a 12VDC power supply but don't know which pins on the unit are Pos and Neg.
Does anyone have a pinout for this radio? Is there a better way of testing it?
Thanks.

Any ideas? Anyone ??
