I flat towed a 2008 Cabrolet for two years, with no problems. Then I decided to change cars, went for a Mini Cooper, bad mistake. Went back to a 2012 Cabrolet. What I need to know is, will the BlueOx BX8848 wiring kit work on the car without causing any problems? I ask this because I do all of my own work to set the car up for towing, and I would rather not have to take the rear off in order to do the tail lights.
