Wiring diagram

[longworth91290]

I've been looking for the wiring of my car radio's cassette player. I can't find it anywhere. It is a two part radio (radio which is then connected to a cassette player that is under the dash) in a 94 Pontiac Sunbird. I'm trying to hook a auxiliary port up but I don't know which wires are which that go back to the original radio. The cassette player is a Delco model #16158302. Any help would be nice.

There are 9 total wires. The only one I know is the constant 12 volt power. The other eight are dark green (with stripe), light green (with stripe), purple (with stripe), blue (with stripe), white (with stripe), orange, red, gray

It will be a lot easier to change the radio out with a new one with aux built in.
