backup camrea

I have a question on factory backup camera.

The camera works great ...put it in reverse and on it comes , I have the 7" screen nave unit. I added a gmx550 to the truck to allowing using the screen to watch movies thru the I pod or a DVD player, It all works great .. This gmx550 also allows you to turn on the back up camera even if it isn't in reverse, but you have to connect a wire from the gmx 550 to the camera...OK here is the question. Does anyone know which wire the camera using to turn on the camera when it is put in reserve, this is the wire needed to connect to the gmx550 there are 5 wires coming out of the camera where it is mounted in the tail gate.. Just don't which one is which, also I wonder if the connection can be made at the MBEC instead of going to the back of the truck where the camera is

Thanks Jim

well any one who is interested , I finally found the reverse wire for backup camera, everyone was saying it was the blue wire in the x10 connector of the MBEC, which is wrong ..that wire is for the backup lights... keep in mind this truck is a 2009 silverado with factory nave and back up camera....The wire that controls the 12 volts to the camera is a lt green wire in the BCM module located just to the left of the MBEC module. If any one is interested I can post pics of it.. Everything works fine now , I can shift to reverse and the camera comes on , then put it in drive and turn on the camera rolling down the road with the GMX 550, Ive been working on this for 4 weeks now glade to have it working
