Running lights to trailers won’t work. Dealers do not know how to fix.
Update by user Aug 01, 2021 Truck will not power running lights on any trailer, camper, etc Original review posted by user Jul 31, 2021 GMC told me to take back to Dealer. Dealer called me, while I was enroute and said, no need to come in-no solution available at this time.
