Expert Reply:

Curt classifies the difficulty level of the installation as 'moderate'. They tell me that a professional installer should be able to complete the installation in roughly 40 minutes to an hour. For a do-it-yourselfer, the install time will depend on you mechanical ability.

To determine if the install is something you would feel comfortable attempting, take a look at the install instructions that I have linked for you.

None of our suppliers offer a trailer wiring harness that is compatible with the 2012 ML350, I would recommend checking with your Mercedes-Benz dealer for a wiring harness.

To complete your towing system, you might also need the following:

Ball mount, part # AMSC2
1-7/8 inch trailer ball, part # 19260
2 inch trailer ball, part # 19247
