Hi, everyone. I'm new to this forum but not to the world Cadillacs. My parents have owned them for years, since the fifties actually. So, anyway, my dad treats his DTS like a really nice truck. He in fact calls it the "cadi-truck" because they can do anything and go anywhere. He's put hitches on them for years. We got a new DTS and sold the old one that had the hitch so it was time to put it on the new one. Problem, it totally screwed up the whole car and it took the dealership 2 days to get it running again. The dealership said it's not possible to put the wiring in. What??? The car is completely capable of towing a load. How do you get your boat to the lake? Has anyone actually done this? Can you give us some advice as to how to make it work? We are currently using the hitch but we don't have any brake lights which is totally illegal and dangerous. We need it to go on vacation so we can tow our boat with us. It's just too long to do it without brake lights on the trailer. HELP!
