Trailer Hitch and Wiring for a 2018 BMW X5

For your 2018 BMW X5 I recommend the popular Curt trailer hitch # 13077. This hitch will fit regular X5 models as well as M performance models. Once the hitch is installed only the receiver will be visible. I have linked a video showing an example installation for you.

For trailer wiring I recommend the ZCI harness # 119250KIT. With this harness you will not have to splice into the wiring on the vehicle like you would with the other available options. I have linked a video showing how this harness installs as well.

I also recommend etrailer ball mount kit # 989900. It comes with 2 ball mounts; one with a 3/4 inch rise or 2 inch drop and one with a 2-3/4 inch rise or 4 inch drop. It also includes a 1-7/8 inch ball, 2 inch ball, hitch pin with clip, and a storage bag.

If the ball mount kit does not have the right rise or drop to tow the trailer level, use the link I have included that explains how to measure to choose a ball mount to tow the trailer level.
