I have a 2011 Silverrado 3500HD. Factory Rear View Mirror Camera. I just installed a new nav unit that does not have the video feed. My M-BEC connector on the left side has the following color connectors: Gray, Brown, Blue, blank, blank My M-Bec connector on the right side has the following color connectors: Gray, Black, Green, Red, blank. I need to know which connector color is supposed to have the video feed. I need a white and blue wire to be routed to the Nav unit pin 6 (White), pin 7 (Blue) to the brown connector on back of Nav. Where is everyone picking off the white and blue wire? The rear camera system comes up to the M-BEC from the rear. The factory then uses a single cable from the M-BEC to feed either the Rear Mirror or the Nav unit but not both. If you are using factory install, parts, and you already have a Rear View Mirror Camera, one would replace the M-BEC harness for the mirror and use one to feed the Nav instead. Both Brand Motino and CubbyCam make the Mirror and Nav M-BEC harness. I cannot tell which M-BEC connector color is supposed to feed the video signal to mirror or nav.
