Does Tow Dolly Towed Behind 2017 Thor Motorhome Need a Brake Controller

Question:

I have a 2017 Thor motor home with a 7 way plug on the back. I would like to pull a tow dolly with electric brakes. I want to purchase a stehl ST80TD and it also has a 7 way plug. Will the brakes automatically work when these are plugged together? Someone told me I would still need to install a brake control box. Hoping this is not true.

You will need to install a brake controller to activate the brakes of your tow dolly. Otherwise they will not work at all.

For a brake controller I would recommend the Prodigy P2 Brake Controller part # 90885. This is our best selling brake controller because of how well it works and how easy it is to setup. This is a proportional brake controller that senses the amount of braking the tow vehicle is applying and applies a proportionate amount to the trailer brakes. This will be the last brake controller you buy. It can easily be transferred to future vehicles as well.

The Ford F-53 chassis your Thor uses brake controller wiring harness # 3035-P to install the controller. The factory plug location should be over near the emergency brake pedal.
