QuestionQUESTION: I have found the colour code for my car and have but on the harness I have there are several duplicate colours. Even when I separate the speaker wire colours there are still two blacks, two dark greens, two yellows, an orange, a light green, a grey, and a purple wire with a white stripe. The remaining wires listed in the schematic for the stereo are orange for car radio constant 12V+; yellow for car radio ignition switched 12V; black/white for car radio ground; gray/black for stereo radio illumination; brown/white for stereo radio dimmer; dark green for stereo radio antenna trigger; and a N/A colour for stereo radio amplifier trigger. How can I tell which wires are for these purpose. I don't have a power antenna and there are some stereo controls on the steering coloum. As well when they list two colours with a slash (gray/black) does this mean that the wire is generally gray with a black stripe or is a choice of gray or black/ thank you for your time.
ANSWER: Hi Jay,
Are you trying to install an aftermarket deck? If so, I'd strongly suggest buying an aftermarket harness for your car instead of cutting the factory harness; it will make your life infinitely easier.

QUESTION: no this is a factory deck for the buick. My car was purchased with a stereo stuck in the hole but not hooked up. probably the seller took out his aftermarket deck and just wanted to keep up apperances by sticking in a deck, that doesn't work. I now have 18 wires grouped in the dash for the stereo and a harness with 17 wires and a schematic for 13 wires, so my question still stands?
AnswerHi Jay,
If you're putting a factory deck into the factory car, the colours shoudly simply match up. In the case of extra wires off the deck, look around for cut wires/missing harnesses beyond that, since some cars have extra wires that don't go into the harness that are used for powering the antenna, or external grounding, etc.
