Hello everyone. I have a 2012 Cascadia isx. Does anyone know what the yellow and green wires are for on the back of radio. I have found all other wires (speakers power memory etc). These 2 I have no idea. They both have power. If I remember correctly less than 2 volts with both being exact same voltage. Appreciate any help.

Maybe dimmer and bunk controls?

Dimmer and steering wheel controls?

Twisted pair? J1939 network.

No. Not that fancy lol. Everything works as suppose to. I wasn’t sure if those was communication wires for computer modules or something like that. I see a lot about j1939 using green and yellow wires. But idk. I’m clueless as to what they actually are. Don’t know what else in this truck would connect to radio

Are wires twisted? J1939 used to program radio, hands free communication, diagnostic, messaging. Even you don't have this options in this truck it could be on the radio side.

No. They aren’t twisted.
