I'm installing an after-market radio unit and am soldering on the new harness to the wires from the factory radio. I believe the two larger wires are the ground and battery (Black w/ white stripe and Orange) and the speakers are twisted pairs (easy). The solid black, solid brown, solid gray, solid green (not part of the speaker pair), and two purple wires are the ones i'm having trouble decifering.

Did a diagram come through clear
Customer: replied 5 years ago.
I can read the diagram looks like my antenna IS or is connected to my read defroster? the purple wires are not on the diagram. There are two inexplicable purple wires.

Do you have the auxiliary amplifier on your system?
Customer: replied 5 years ago.
No amplifier that i know of. I looked at scores of forums and looked in the places where others had them. No amp in the trunk behind the carpet on either left or right sides. None under seats or in dash that i can find.

I understand you have no amplifier on just saying that that wire in the harness goes too the amplifier when you have an amplifier that's what it is for apparently it's just terminates
