We are currently towing a 2016 GMC Acadia behind our Georgetown 351DS. This is a new vehicle, replacing a 2009 Saturn Outlook that was involved in an accident. The Outlook and Acadia are basically the same vehicle.
We went with the Blue Ox components, and both vehicles require pulling a 50-amp fuse from under the hood. The 2016 Acadia also recommends pulling the OnStar fuses which are located in the battery box, which of course is located under the floor behind the passenger seat (I would've never found that....lol).
In the Outlook I had purchased the Blue Ox fuse bypass switch for this vehicle (BX88271-BX88274, BX88294 Fuse Bypass Switch | Blue Ox
). It was simple to install in the fuse box, but not the easiest to get mounted for use, and they've gone up in price quite a bit. Simple to use however, a quick flip of the switch and you're done! They also offer a switch for the OnStar fuses.
My question is this - for those of you who pull fuses when flat-towing, do you use a bypass switch? If yes, did you buy or build one? I'd love to just wire it all up to some switches on the dash or inside the glove box, but I'm not an electrical expert by any means. Just looking for some advice on wire gauge, types of switches, stuff like that from anyone that's done something similar.
Thanks for any help!!
