I should have realized it would be difficult to reconnect the intervehicular cable to the electrical harness on my M101 CDN 2 trailer by how difficult it was to disconnect it. The manual made it sound sooooooo easy. "Unplug the intervehicular cable (5) from electrical cable (6)." The problem is the connections are "hidden" in a boxed section of the frame and difficult to get to. Unlike the M416 that are quite accessible. Does anyone have a "trick" to make it easier the reconnect the cable? Or am I just going to have to fight it?
