OK, so you want me to run down what the different wires on the radio do or what? I would think that if you look at the original wiring on the RADIO side, and look at what they are attached to (colors of wires) then maybe you can spot something not correct.
For example if there is a red wire on the radio side, and they have it attached to a yellow wire for example, then that is incorrect. Can you remove the radio yourself, or need help?
