Radio wiring

[NDHutcheson]

Good afternoon,

Can someone please validate which of the plug wires on the picture attached, the single wire or the two wire is the ground? I assume the single wire is the ground as that plugs to the black wire in the factory radio.

Also Curious why there is two wires coming out of what I would consider the positive side of this connection. Power antenna??

Hooking up a new slide bar radio and I want to make sure that I get the polarities appropriate. Thanks so much!

Neither. The white/purple lines are radio power; the blue/red wire is lamp power. The radio is grounded through the chassis mount.

Thanks so much for your response. I knew the ground was with the bracket, and it slipped my mind. But thanks for identifying which wires in that two harness. I will move forward with installing my new radio.
