This weekend I purchased and installed trailer wiring to our 2022 bolt euv. There was no how to for the euv, I started with the how to for the 2022 ev but quickly realized that it would not work.

Now regarding the 12v + always on pick up from the gray / violet wire in the liftgate harness. I have it wired that way now but not sure its ideal. In the GM upfitter document, in the liftgate jumper hasness (wich I think is the liftgate harness), it shows as “Windshield Wiper Moto, Park Switch, Fused Signal” is this a good power source? I have tested it and it works but havent turned the wiper on at the same time tho 😅 What else would you recommend beside wiring all the way up front to the battery? --------------- There should be a 12V hot in the left side blinker bundle for towing/accessory so you don't have to run all the way to the battery =========================================== https://www.reddit.com/r/BoltEV/comments/155a5jk/comment/jsvdh9s/ I didn't take any photos, because it's already well documented in the link you sent. HOWEVER, in the '23 model, the "trailer control module" has been eliminated. There's two places you'll need to tap into. The Liftgate harness; located to the left of the module you pictured, following the thicker bunch of wires you'll eventually get to a plug. This plug feeds the hatch with running lights and power. You'll get 12V power and running lights from there. Note: when testing the running lights that feed off this "upper" harness, you won't get a signal unless the hatch is closed. The bumper harness; this one you follow the bunch of wires to the right of the module, back into the car until you reach another fork of wires that runs down. This bunch of wires that run down actually runs outside the vehicle into the driver's rear wheel-well, and that feeds your bumper with turn signals and brake lights.

Airbags in the rear springs [2] apparently improve the ride and prevent bottoming out with a heavy tongue weight. My teardrop camper weighs only 600# though so Im hoping to not need it The best trailer hitch seems to be from Torklift (its the one I have) and rated for 2000# https://torkliftcentral.com/trailer-hitches/rear-mounted-receiver-hitches/ecohitch/chevrolet/2017-2023-chevy-bolt-ecohitch [1] https://old.reddit.com/r/BoltEV/comments/14xy7qg/video_towing_our_teardrop_trailer_1000_miles_to/ [2] https://www.airliftcompany.com/vehicles/chevrolet/equinox/2023/#l
