    X3 Factory Trailer Wiring Kit Help

    I purchased the factory trailer wiring kit from Turner thinking that this would be the best method as most of the accessory kits would have you cutting wires. No instructions came with the kit and from what I can find out online it is quite a job that also requires the dealer to reprogram the computer. Could someone direct me to a good set of instructions on installing this kit in a 2007 X3? Also some idea what sort of reprograming is required?
    I'm kind of stumped and starting to get cold feet.

    Sorry I couldn't have helped, Tom. I try to answer in places I have some experience. Here, I had nothing. I'm glad you found some help elsewhere.
