I'm towing a 2015 Acadia. Baseplate installer put a charge line in to keep the battery charged. GM folks said that since I have a charge line I don't have to pull the 3 fuses---but if I don't pull the batt1 fuse the odometer will accumulate mileage while towing. So I'm pulling the Batt1 fuse under the fuse. Now to my question: shortly after pulling the batt1 fuse there's a click and the headlights come on. Not the daytime running lights, not the tail lights----only the headlights. Turning the automatic lights off before pulling the fuse--lights still come on. Now here's the puzzler: there's apparently a timeout because after I've towed for a couple hours I can put the fuse back in then immediately remove it and the light will go out and stay out. So other than pulling the other fuses, how do I keep the headlights from coming on---or has someone figured out the time delay?

My thought is something is not right somewhere. There is more than one Acadia\Traverse\Enclave being dinghy towed, so I would think if this was the norm, there would be at least one post about it on the forums I frequent. I would double check your connections.
Do you a search on here for Enclave, Traverse, or Acadia, send a message to those that posted, ask them if they have had the problem. The threads I read only mention the 3 fuses.

I have the same vehicle and the same problem. The only solution so far is to also remove the two high beam fuses. I found that with the Batt 1 fuse plugged in but not the high beam fuses I can drive and and manually turn on the low beams with the headlight control knob. I installed the Blue Ox fuse switch on Batt 1 fuse to avoid having to manually pull fuses. I'm glad to hear that this is not unique to my vehicle. I also installed the Blue Ox 4 diode kit on the tail lights. Calls to GM and dealer were fruitless.

The plot thickens. After 45 minutes of towing we made a fuel stop. Headlights on the toad were on. Put the batt1 fuse in momentarily then removed it. Toad headlights turned off and stayed off. They were still off when we parked 5 hours later. Go figure. Must be a time delay at work. I'll try to refine it and get it down to a more precise figure.

I installed another Blue OX fuse bypass switch on the Left and Right High Beam fuses that I have to open the hood to access. The Batt 1 switch and the ECM and OnStar fuses switch are installed under the dash. This way I can start the vehicle at fuel stops or the morning warm up without having to open the hood. I almost have as much invested in Blue OX switches than I spent on the baseplate.
