Hey guys, got my D3 unit in today that was purchased used. But it looks like the harness is missing the VSS and reverse wires? Also the teal wire you see in the picture is the hand brake wire correct? Here is a picture of the harness:

What should I do?

also, i know the yellow/black wire is the mute wire where i have to ground it to bypass. but what/where does the blue wire do/go?

Yeah the light green/teal wire is the parking brake.

That blue wire in the AV harness shouldn't even be there.

Thank you, I just bought a new power harness since it was missing the VSS and reverse wires. So I can leave the blue wire in the AV harness alone right? I'll just wrap it up in electrical tape or something.

Yeah, you can leave that blue/white alone. If memory serves me correctly, blue/white is for a powered antenna connection, but I'm pretty sure that would be on the power harness, not the AV.

Although it's been a long time since I've seen a D3...
