I am considering a 550 Ultra. Anyone out there towing with a Tiguan? Did you order your CI with electric brakes? Are they needed with a Tiguan? I know there is an expensive computer module for trailer wiring that you need from VW and then the CPU and the Tow Module must be reprogrammed -- did you have any problems with the CI's LED lights with the VW wiring module? Finally, how did you wire the brake controller & pwer back to the 7-pin?
