    Factory Trailer Wiring Kit

    Has anyone installed the factory trailer wiring kit? I got one from Turner that came with no instructions and from what I can find out online, it is quite a process that includes reprogramming the computer. I'm starting to get cold feet.

    You can install it by the driver rear light and tap in there. You'll need to run one wire to the passenger side also and wires to the battery for power and ground if that helps identify the wires. One L one R one STOP/RUNNING one + one - shouldn't need any programming (mine didn't )

    I realize this is a little late but I only just picked up an X3 ('07) to be able to tow my boat and stop using my E36M3 vert as a daily.
    I installed the factory Tow Hitch and wiring (got mine from ECS but it's the same kit). The wiring harness plugs into a plug near the little "bucket" at the back on the passenger side ans a computer module plugs nicely into a spot under the cover just behind the back seats (forward of the battery and tools compartment) and there's even a factory spot to screw it down with the included nylon nuts.

    Hope I haven't resurrected a zombie.
