In the Saturn, a GM car, I only pull one fuse. I believe from reading the Traverse has one fuse for the Aux system (dashboard lights) and one for On-Star, not sure about the third. But just install a disconnect switch into each fuse slot and off you go. You can purchase them, or make them, I made mine. Take an appropriate fuse, short it out, solder leads to both test pins on the top of the fuse, run the wire to a reachable location and install a new fuse clip. Then just pull the reachable fuse when needed. Or purchase a pre-made switchable connector. I'm also thinking of the Traverse as it will hold the grandkids if we take them on trips. It will be a bit heavy for my gas Adventurer, but I may add the Banks to the engine.
Happy Trails.
