Question:

Need a 7,000 lb hitch for 2012 Mercedes ML350. Curt III vs Draw Tite #76141? Is Curt good enough? Need wiring. Do you have a package deal?

I do have all of the parts that you need but there is not a package with all of these components available.The Draw-Tite Max-Frame Trailer Hitch Receiver part # 76141 is the only option for a 7,000 lb weight capacity hitch on the 2012 Mercedes-Benz ML350 as long as it does not have an active curve system. Please keep in mind adding the 7,000 LB Draw-Tite trailer hitch will not increase the towing capacity of the vehicle itself. I have attached an installation video for your reference.

Since you need wiring, I recommend the ZCI Circuit Protected Vehicle Wiring Harness part # 119250KIT which is the easiest installation available for the Mercedes since there is not a custom fit wiring harness available. The ZCI will clamp to the factory wiring instead of splicing into the delicate wiring to install. I have attached a video for your reference for this install as well.

If you plan on doing some towing you may consider the 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 you are not sure how much rise/drop you may need in a ball mount to tow your trailer level, I recommend to take a look at the helpful article I have attached about how to figure the amount of rise or drop you may need.
