Hi there, I have integrated trailer brakes and when hauling my fifth wheel my "check trailer wiring" warning flashes when I put on a blinker. When my lights are on its keeps flashing over and over. It also gives me the "service trailer brake system" warning a lot and shuts the brake system off. All the lights on my trailer work. When I first hook my trailer up nothing works and after I drive for a while it all starts working but the warnings still appear. It seems like a ground issue or something. Any have this problem or have any ideas? Also, both my truck and trailer have been lifted if that helps..

Some trailer brakes are not compatible with the onboard controllers without a special adapter. You might want to contact the trailer builder for advise.
