1994 c1500 4.3. putting an aftermarket alpine in. the stock radio has no plug. wires are just soldered into the board so no aftermarket adapter pug will work. i know where the orange, red, and the black wires go on the alpine but the stock harness has only 3 more wires for 4 speakers. the alpine has probably 8 more wires. anybody know how to get this to work?
thanx

 

Are you trying to interface with the radio control head in the dash, or the actual radio reciever under the drivers side of the dash?

 

didn't even know there was a receiver under the dash. took the one out of top right of dash going to put a cubby hole where the dash one was. i'll look under the dash when i get home.
thanx

 

ok the under dash receiver only has the one plug going to it that goes to the dash controller. there is an empty plug receiver next to it.i know there has to be another plug because the one i see is hot. is there an easy way to take the under dash out?
not really much of a mechanic and need help.

 

well bought a book. got the radio out from under the dash. having a harder time trying to get the ash tray back in. jeez starting to think this thing might be a ford in disguise.
