What 7-Way Circuits Need to be Active for Prodigy RF Brake Controller TK94FR to Function

Question:

We have a customer with a 2013 MB ML350bluetech. She is going to tow a horse trailer with her vehicle. She has a factory trailer hitch set up with a 7 pin factory plug on the car. We are going to purchase a # TK94FR controller set up. Is this all we need??

As long as the 7-way on her 2013 MB ML350 Blue Tech has the 12 volt accessory circuit active (as well as normal trailer wiring circuits), the Tekonsha RF part # TK94FR would be all you need and would work well towing the horse trailer.

I attached an install video for this controller for you to check out as well.
