GREEN/ ORANGE is the speed sense wire. This wire is 4000 pulses.Found at the ECM behind the glove box. The reverse wire is for GPS and also for rear camera activation.

The speed sense wire is to let the navigation system know your speed of the vehicle so it can calculate ETA for arrival times on trips. The ECM will be a larger metal casing with large connectors with hundreds of wires coming out of it.

ok i found the vss wire, its is a green wire in the ecm. now where would i find the reverse wire other than at the tail lights. figure it would have been in the console area but i didnt find it. and what is the purpose of it for the nav, is it necesary?

Yes it is neccessary. The nav relies on a system called "dead reckoning". What this means is that it will aquire your position by sattelite when it starts up and then switches to your vss wire, reverse wire, and a gyro inside the unit to tell you where you are. Reverse should be running down the running board.

the vss wire i found but a multi meter, it fluctuates with spped, while still has nothing, start moving it reads ac voltage. i'll look again tomorrw for the reverse wire, just had wisdom teeth pulled today so im a little out if it. any clues to what color to look for for reverse wire? nad that is the wire for the back up light? right? LOL

I don't know the color, you can pull the tail light and find the color for the reverse light easy. Also your speed sense will go between ground and nothing when moving slow (I only roll the vehicle a couple of feet forward and reverse to find it).
