May I suggest a less expensive alternative? I Have a 15 GMC Acadia which is mechanically identical to Enclave. I have to pull the 50 amp "batt 1" fuse under the hood: doing that keeps from running the battery down and prevents mileage from accumulating while towing. Much easier to do if you go to an auto parts store or the dealer and get a high profile fuse. It's about a quarter of an inch taller and you can easily grab it with you fingers and pull it out.
