Getting the systems in the center tunnel corralled has long been on my list. This goes hand-in-hand with prep for the stick grips, which also require a clean exit from the tube, and insurance that none of the wiring will infringe on the stick movement–even as we add a massive 9-strand cable into the mix.
I’ve tried about every type of foam I could find to create a guide for the center tunnel, and finally found a yoga block that was dense enough to work. I create three-four spacers, much like the foam spacers they put between your toes during a pedicure (I wonder if those would have worked…), to space and tidy everything running fore-to-aft in the center tunnel.

I’m really getting happy with how all of the wiring organization is turning out.
