How To DIY You must read the instructions that came with your brake controller and follow them. Some brake controllers need to be mounted at a certain angle and higher power controllers use larger wire and breakers.You must also read your WKs owner’s manual and see what your towing capacities are. Failure to do so has resulted in death.

It turns out that pressing the electric brake controller lever does not disable the cruise control so keep that in mind.

My conversation about the U-Haul hitches is sort of unrelated as their trailers come with hydraulic brakes in most cases. If you are going to rent a U-Haul trailer you should buy your hitch draw bar and ball from them to ensure it is rated for enough weight. A lot of places will sell you a 2000 lb ball but they are not suitable for U-Haul trailers even though they will hook on to them.
