Question:

I have a 2011 ML350 Bluetec with standard dealer installed hitch. Vehicle has standard lights and wont work with one of my trailers with LED lights. Will your TR20141 adapter work with my vehicle or do you have another that will allow use with an LED trailer.

Expert Reply:

If you have a 7-way on your 2011 Mercedes ML350 and when you connect your trailer with LED lights you end up getting a bulb-out error code the 7-way adapter part # C35FR will work for you.

There are load resistors in this adapter that increase the amperage draw of the vehicle's trailer wiring so that the vehicle does not think it has a blown taillight bulb.

If instead your trailer has a 7-way connector you would instead need the part # C57003. The # C35FR will convert a 7-way to a 4-way.
