I certainly can provide a link to the installation instructions for Draw-Tite Trailer Hitch, # 75376, for your 2009 Mercedes ML350 below. We have estimated the difficulty of installing this hitch at a 5 out of 10. Difficulty is measured in terms of how long the installation should take for a novice installer. We estimate it should take about 50 minutes with all the proper tools and perhaps an assistant.
The installation does included some drilling (see step 7 in the instructions linked below). If you plan on doing some towing the recommended ball mount is # 2923, and you can use ball # 19260 (1-7/8 inch diameter), # 19247 (2 inch diameter), or # 19287 (2-5/16 inch diameter). For trailer wiring, it is recommended that you visit a local Mercedes dealer and have them install the vehicle specific harness.
