Does anybody have the Part # for an '07 ML Trailer Wiring Harness, the one that plugs into the SAM. I have an R class and apparently the ML Wiring Harness is plug and play according to Sounder who went through some aggro to get this Harness. According to my local dealer they only have a part # for the entire ML trailer hitch, but not a separate number for the Wiring Harness.

Thanks in advance.

 

The rear sam must be replaced also if memory serves me correctly.

 

Call the parts department you can order the one you need. It goes by year and Vin#

 

The MB dealer will put a class III hitch on my 2007 ML350 (5000 lbs hitch with 500 lbs of tongue weight) but that gives up some of the 7200 lb towing capacity. I want to tow a travel trailer (Airstream weighing about 4500 lbs). Has anyone put a class IV hitch on their ML? I'd appreciate any tips on wiring, etc? Thanks.

 

Do you know what is required on the 2008 ML320?
