I dont really have any comments about the Gerbings - temps where i live only dip to 20 deg C in winter, so no need...
I do have an Autocomm fitted. By using an extension cable, my rider outlet runs forward from under the rear seat, and emerges through the rubber boot inside the fuel filler cap, under the flap. When not in use, the cable is completely hidden and protected from the weather by the flap. When in use, I uncoil the cable from around the fuel filler, run it out from under the flap and plug in. Keeps the cables in a forward position, away from legs, and does not interfere with the bars in any way.
You will need to take a round file and make a small semi-circular slot (say 4mm diameter) in the filler flap at the trailing edge, so as not to place undue pressure on the cable. Not noticeable at all, and can be replaced if required when you move on to your next LT.
The pillion cable emerges from behind the rear seat, through the gap between the upper and lower cushions. Can be just tucked away when not in use, again out of the weather. I chose the L/H side for this, but not for any particular reason.
Nett result: easy access, no cables in snaggable (new word) positions, out of the weather, nothing to see when bike parked or Autocomm not in use.
I can put together some pix if this proves of interest.
