I have a 2010 Equinox, this is what I did: I had a battery disconnect at the battery put on similar to the shut off switch on the RV battery. Mounted it on the back side of the core support. I ran a power line off the positive post of the battery with a fuse to inside the vehicle and mounted left side under the dash lower plastic dash panel to run a Brake Buddy. Brake Buddy will provide this kit for free if you call them.
When I tow I put the vehicle in neutral , ignition switch on, disconnect the power and nothing will show as to mileage. No longer need to pull fuses.
