I've followed the thread on the flat 4 pin wiring here: http://gm-volt.com/forum/showthread.php?40161-HOW-TO-Trailer-wiring-harness&highlight=trailer+wiring and it is still helpful after all these years. However, I have a 7 pin situation to charge a battery while running. I'm not certain how this would work or if it is even advisable. I could easily live with just the 4-pin for running lights, brakes and signals with an adapter to the 7 pin connector.. My camping is going to be limited to "proper" campgrounds with shore power for at least a few seasons so the battery charging from the car isn't at all critical but a "nice to have" option down the line.

Has anyone done this or know how to adapt the info in the linked thread to accommodate the 7 pole connector?

Disclaimer....I'm not going to do the wiring. An RV shop is. But the Volt is so different from an ICE setup (I know they haven't seen one yet) I'd like to be careful in advance. If I can prevent a bad situation I'd like to.

It's just like any other car. Grab 12V from the battery and run the wires to a 7 pin connector. If the RV shop doesn't know that, find a new shop.

So long as the trailer doesn't require a brake controller...

(you could install one, but generally speaking a trailer that has it's own brakes is way too heavy for the Volt)

No brakes. Just lights, brakes, signals and a line to charge the battery on the trailer (which is 600#)

Should be possible to follow the 4-pin guide then, plus add a fused wire to the positive terminal on the battery under the trunk.
