Does the Trailer Wiring for a 2011 BMW X5 Have to Route Through the Rear Door

Question:

Hello, Im looking to purchase wiring harness kit for 2011 BMW X5 119250KIT. Question: Is there a way to have the plug part that connects to trailer mounted next to the hitch receiver instead of having put it through the door? I have CURT hitch 13077 Thank you!

If you can find a grommeted hole in the rear cargo area of your 2011 BMW X5 you could route the 4-way through that, but you should note that it is actually preferred to keep the trailer wiring stored on the interior of the vehicle.

Having it stored there keeps it protected from corrosion and damage from debris that could be flying around under the vehicle as you are traveling. The thick rubber seal on the rear door frame will protect the wiring as you shut the door on it as well.

I attached an install video that shows this harness being installed in a 2011 BMW X5 just like yours.
