Sony headunit wiring help
I just got a headunit from my cousin that he had in his truck awhile ago, the wiring harness is here but some of the wires are not marked.
It is a sony cdx-c780, is it any good?
On the wiring harness there is a black wire unmarked
a orange and yellow wire unmarked but hooked together, i'm assuming those are power?
a red wire unmarked
a blue wire with a white stripe marked amp rem max 0.3A and a dark blue wire marked ant rem max 0.1A, what does all that mean?
also I'm guessing the light blue wire marked att is antenna? if so how do I hook it up to the stock antenna wire?
thanks to anyone who can help even the least bit.

Red- 12v Switched
Yellow - 12v Constant
Orange - Illumination...no need to hook this up unless your truck-side wiring harness has it as well. hooking it to constant just keeps the lights on the head unit constantly dimmed.
Blue/white - amp turn on. No need to connect if there is no aftermarket amps.
Blue - power antenna. You dont have a power antenna, so nothing to hook it up to
