The only thing I can help u with right now is the RCA outputs. As long as they are not preamped, u can amp them.

All of these wires u are talking about, are they on the car, or on the radio?

If the orange wire is on the radio, it is most likely for the dimer for the radio. If u hook this up to your headlights, the radio will dim the lights on it.
