If you are going to install the radio, I recommend you get a wiring harness specific to your vehicle. It will have the color codes on the package. All aftermarket radios have standardized color coding for wires. hope this helps

It is what do they call color coding . Like example white goes to red wire or blue connect to orange . In radio ,the positive charge connect to the positive and the negative negative connect to the negative, there is a wire that should be connected to the ground and the wire that should be connected to the battery.

here are the wiring for the deck and the car:
Deck:
12v - red
ignition: yellow
blk - ground
orange - dimmer
white - frt left +

Get a new unit. The damage was done before the smoke was present.

Most aftermarket radios follow the same color code. W G G P, White, Grey, Green, Purple. LF, RF, LR, RR. red is switched ignition, yellow is constant battery, black ground.
