This is off of a '92 gamma non-bose radio. I'm adding an aftermarket HU and I need some help. I pulled new speaker wire throughout the car. But I have some wiring questions to connect my new head unit, I know which symbol is the ground, but I dont know
1. which wire is the constant power from the battery?
2. which wire goes to the ignition switch.

See where all the plusses are on the top plug. Get a volt meter and with the car off check them all this way u'll find the cosntant power to go to the yellow wire on the radio. Then turn the ingnition on and see which wire has power only w/the ignition on, that's ur remote power and it goes with the red wire on the radio. The rest easy.
