I just bought this Grand Am with a monsoon radio system (I know it has monsoon because the factory radio is sitting on the floor). The problem is that the previous owner cut the factory wiring harness too short to reconnect and now I am having troubles figuring out which wire is what. I ordered a metra turbowires harness 71-2003-1 from Amazon but it has more wires (24) coming off of it than the factory harness had (18). The colors from the new harness that I ordered are also different than the factory wires coming out of the car. Can someone please tell me what the easiest way to either reinstall the factory radio or an aftermarket radio is?
The factory wiring harness has these colors....
Row A is:
12. black/white
11. dark blue
10. light blue
9. grey
8. tan
7. light green
6. pink
(5,4,3,2 do not have any wires)
1. purple
Row B is:
12. brown
11. light green
10. dark green
9. yellow
8. brown but smaller gauge than other brown in row b(probably speaker)
7. no wire
6. purple
5. black
4. gray
3. dark green
2. no wire
1. orange
