Hey 007, I've got one for ya. I'm trying to run a 3.5mm cord from the back of the stock auxiliary input (in the upper dash) to the back of a CB radio, turning the car speakers into speakers for the CB, blasting whatever is on the CB radio to the car speakers. I have a 3.5mm auxiliary cord that I cut, yielding a red wire and a white wire. I (foolishly) assumed that there would be two wires running into the back of the stock auxiliary input but pulled the wiring harness out to reveal six wires...
As you can see, the wire colors are yellow, blue, black, brown, green, and gray.
Based on a wiring thread you posted, I believe four of the wires to be positive wires coming from four speakers. Any idea what the other wires could be? I thought I would just be able to splice the auxiliary cord in with the wiring harness but was stumped when I found six wires. I appreciate any help!
