I know from my wiring diagram and from the wiring in the door panels, that the front right speaker wires are supposed to be red/white. However I removed the insulation from the harness in the cabin that leads to the door, and I don't see any solid red/white wires in it.

Does anyone know if there's a change in color once it gets into the cabin? Or maybe I'm looking at the wrong harness?

According to my wiring diagram it's supposed to be red/white all the way through to the head unit/amp, so there should not be a change if I'm reading it correctly. The harness I opened was the thick harness that runs along right over the top of the ECU. There's also a smaller harness that's taped on to it, but that seems to lead somewhere else.

I'd appreciate any help, thanks!
