Title: wiring a radio into a 1976 c10, which stock wires are which?
Post by: aleighs1990 on April 10, 2014, 05:12:26 pm

I am wanting to install an aftermarket radio I've had for a while, in my 76 c10 that I haven't had long. It appears there are 5 wires (2 plugs) for radio hookup. I know that the green and black in one plug are for the dash speaker, but which of those wires is which (+/-)? Also, the other plug has a yellow, a black, and a grey wire. What are each of those wires for. Also, I don't have money for more speakers right now, so which channel, of the 4 my radio has, would sound best hooked up to the one speaker?
