I doubt that brake controller will work for electric trailer brakes. It's designed for hydraulic brakes on a toad. If your enclosed trailer has the usual electric trailer brakes, then you'll need a trailer brake controller for electric brakes.
I'll move this thead to the toad forum so the toad experts will see it and maybe give you a good answer.

I will be pulling a 20 ft enclosed trailer- My question is can i wire a 7 pin in place of the six and use the output of this controller for trailer brakes or do i have to install another brake controller for the trailer? The controller has a manual knob that slides up or down in a slot to increase/decrease power.
Grumpy ole man with over 60 years towing experience. Now my heaviest trailer is a 7'x16' 5,000-pound flatbed utility trailer, my tow vehicle is a 2019 F-150 Lariat 3.5L EcoBoost SuperCab with Max Tow (1,904 pounds payload capacity).
