Not sure I am on the same wave length as you, but there is a special little piece under the slides that holds up the wires.
When we were at the plant tour a few weeks ago, Mark showed us one, he said that they had designed it, may have had a patent on it at one time, but thought other units now had the same thing. It was black, a piece of plastic, it was flat, it had some holes it in to put the wires through and the plastic bends when you close up the slides.
Maybe you could run over to that dealer of yours (by the way, NICE PEOPLE THERE!) and ask to look under a newer unit and about this piece. Maybe you had one, and lost it?? With all the road miles you had, that would certainly be understandable.
I would think you could order a replacement part???
I'll be back to edit this if Al finds anything wrong with my response when he reads it.
