Guide for Installing Trailer Wiring 4-Way on a 2012 BMW X5  


I purchased this kit for 2012 X5 but it didnt come with a wiring diagram. Can you email me one.

I can show you a wiring diagram for the # 119250KIT but what I think you will find even more helpful is the install video link I attached to this page that shows this kit being installed on a BMW X5 just like yours. I have attached an install video on a 2013 and a 2015 for you.

This will show you exactly which wires to use for the harness and how to find them.
