This might be a weird question....and if it wasn't pouring out right now I might be able to go digging....but does a 2013 with a factory installed trailer package already have the pigtail for a trailer? And if so where is it located?

I need to rent a trailer and was wondering.

Appreciate the help.

 

Yes, the large round plug with dustcap is located underneath next to the receiver.

 

Thats great news. Thanks. Will take a look when the rain stops.

I appreciate it the info!

 

Note that you will need a 7 pin to 4 or 5 pin trailer converter. The converter also needs to support LED trailer lights otherwise the ML 350 will detect lamp out.
