Question:
I NEED A WIRING CONNECTOR AND TRAILER HITCH FOR A 2007 MERCEDES ML320 CDI. I SEE THAT HITCH, BUT I AM NOT CLEAR ON THE WIRING KIT NEEDED. IS THERE ONE THAT PLUGS INTO THE CAR? I GOT ONE FROM YOU GUYS FOR A 2012 ODYSSY AND IT WAS GREAT - HOPING FOR A SIMILAR EASE OF INSTALLATION.

Hey Jim, thanks for the information and welcome back!
The only hitch we have for the 2007 Mercedes-Benz ML320 CDI is the Curt item # 13342. This is a class III hitch with a 2" receiver. Please note it will not fit if your ML320 CDI if yours has the factory air ride suspension.
Your options for wiring harnesses are not going to be as easy as last time though. There are no plug in 4-way or 7-way connectors for your 2007 Mercedes ML320 CDI. Which means you'll have to go with a universal connector that needs to be spliced into your factory wiring. The most reliable one is going to be the Curt item # C59496. This will give you a 4-way harness for controlling a trailer or accessories lighting functions. A circuit tester is included to help you find the right wires.
What type of trailer are you pulling? You can add this information and any other questions you have where it says Reply to Jerred H and I'll be happy to answer them.

Thank you Jerred! I have these in my cart - just need to sell the old car (that has one of your hitches and wiring kits on it too), before I buy another hitch. This is perfect!
