Hi All.

I've recently installed the AVIC-Z140BH for my 2004  Lariat. I've been trying to find out where to connect the wire from the head unit that is suppose to go to the "Reverse Gear Signal Input. I've seen conflicting post as to the wires color and location. Also I have started getting a message when I first start the truck that says "Images may appear in reverse"  What is that all about ?
