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.

 

The color is a perfect match. Have to tap it at the amplifier in the passenger side floor board for a 04' model and a 05' was plug and play I was told. I used the green and white I believe...it is the small wire. It will stand out for sure. Keep in mind it will be verified by the unit and it will read in large numbers like rpms, not mph.
