Question:
I have a part #75087 hitch installed on my 1998 ML320 with a 4 pole plug. My Casita travel trailer is fit with a 7 way plug. I know that I can just use an adaptor, but was wondering if there is any way a 7 way plug can actually be fit to the vehicle itself?

Helpful Expert Reply:
Yes, to install a fully functional 7-way on your 1998 Mercedes ML320 you would only need the Brake Controller 7-Way Installation Kit part # ETBC7 plus a brake controller.
For a brake controller I would recommend the Prodigy P2 Brake Controller part # 90885. This is our best selling brake controller because of how well it works and how easy it is to setup.
I attached installation instructions plus an install video for the # ETBC7.
