Which Trailer Connector is Included With Roadmaster RM-2050-1 Tow Dolly


I have a 2018 Thor ACE 29.4 F53 Ford that I want to use tow dolly RM-2000-1 to tow a 2016 Honda Odyssey. The F53 is pre-wired for a trailer brake and Ive got a Ford Cable and a Tekonsha Prodigy P3 Trailer Brake Controller in my shopping cart. Does the RM-2050-1 not come with a 7-wire connector? Do I have to change the entire wiring harness? Picture provided is what I believe to be the brake controller connector under dash to connect the P3.


Expert Reply:

Roadmaster does not provide a trailer connector with the # RM-2050-1 tow dolly. If you want the brake functional, you'll need to install a 7-way trailer connector like # PK12706.

It does appear that you've found the correct connector, to install your Tekonsha # 90195 P3 brake controller, you'll need the # 3035-P harness..

I've linked to our trailer wiring help article which features wiring diagrams that show how the 7-way would be wired.
