I have just installed an Infinity Navigation Radio in my crossfire which is the one they offer as an option from Chrysler. Everything went fine til, I had to hookup the speed signal and back-up signal wires. The instructions show where to make these connections which I have found but the color codes for the wires are different from what they say they should be. They are saying the speed signal wire should be gray/yellow but all I can find is yellow/black and yellow/brown that's as close as I can find to that color. As far as the back-up signal wires the instructions show dark green/white wire but the wire that is there is light green. There is a green/white wire but not at the corresponding spot they say to tap into. Does anybody here know what color these wires should be in these wiring harnesses? I would appreciate any help to get me in the right direction. I've checked some other posts but came up with nothing. Thanks for anybody that can help me.
