Get the right cable. Yes on camera-source.com. But Ford has more that one rear connector design and in my case there are two connectors for the tailgate, one is probably for the lock. The camera plug is the most variable one according to camera-source. The longer cable was perfect to reach the long rear overhang on my Lance. You will lose the guide lines that are on the Ford cam but at least backup vision is restored. Maybe the Ford cam keeps the lines. Also, Ford provides dummy plugs for when the tailgate is off to prevent contamination. One of those dummy plugs had to be installed for the second unused connector after my tailgate removal.
