Good luck with your quest, one thing I've read in these forums is that GD uses complete runs while they wire the trailer. But it looks like they wire the trailer and the slides separately and when they set the slides, they make the connections for the two. This included the electrical in my trailer too. Also where the power booster is located, this is where your cable wires meet and get routed to the different locations. I spent a good month looking and contemplating what to do, and getting a feel for how the trailer was built. Again, good luck in your search.
