QuestionOk I have a 1989 pontiac grand prix 2 door coupe and I am having a lot of trouble figuring out which wires are for what. Here's what they are: My friend took out the equalizer and coming from that area there are three wires that are: green, Yellow and Grey. Then in the main bundle of wires there are 1. solid white with green strip 2. solid yellow 3. solid orange 4.brown/tannish with white strip 5.black 6.brown 7.orange with black strip 8.black with white strip 9.yellow with black strip 10.green with a pinisk flesh color strip 11. green and then there is a bundle wrapped in what looks like electrical tape in with the main wires, this bundle contains a 1. Brown and white 2. green and white 3. no covering only metal wire PLEASE someone help me with figuring out which wires are for what, my friend already trip the whole battery test with little returns, we need a wiring diagram that matches this or is close.
The model number on the equalizer is 16075827
and I believe the model number on the cassette/radio part is 16050912
AnswerWhile that is a neat and graphical story, I do not know the stock wiring codes.
I presume you want to upgrade (since all you really explained was the wiring colors).
At this point, most any pro will tell you to install all new wiring and go from there (as to upgrading the system).
If you want to upgrade without cutting wires, you should approach it that way, as there are wiring adaptors that not only adapt but have the wiring codes for them once they are installed.
I cannot help you much more with such little info as to what you are actually trying to accomplish.
