We've also been wondering about how to get cabling down to the rest of the "electrical parts" of the rig...
My best guess so far: Run a small diameter PVC pipe down the side of the rig. (In a place where it's safe and wise to do so...
). Use it as a conduit. Seal the top of it, and once you've got the wires down to the bottom of the rig: you can run them up "underneath her skirts".
