The cd player that was installed in my car, not factory, has since quit working. The wiring is marked for the speakers, but other than that it's a guessing game.
There's 3 red wires(+) 3 black(-)wires' a thick orange wire that's hot, and multiple other wires coming from under the dash, above and beside the relay panel(behind radio/ashtray assembly).There's 2 factory amps. in the car, 1 above the driver's floorboard, 1 mounted in the trunk.
By messing w/the wires I got the radio to work, as well as another radio I tried to make sure it wasn't just the original one not working. When I tried to install it back into the car it quit again, as if something shorted it out.
Is it possible to find "good" wiring diagrams online for my particular car/radio, if so where?

Thank You

 

If all else fails run your self a new Ground wire and power wires to the radio.
You will need 1 ground wire. One switched with the key. And one hot all the time.
