How to Attach a Wiring Harness to a Hitch on a 2021 Toyota Sienna  

Question:

Hello, I was curious if either of the hitches Drawtite or Curt for a 2021 Sienna Hybrid have any sort of hardware set up for the wiring harness. For our Sprinter, I could attach a bracket to the hitch I bought that would hold the wiring in place rather than just having it dangle around.

We do have the Tow Ready No-Drill Mount for Electrical Mounting Bracket # 18140 and Mounting Bracket 4-Pole Flat # 18144 that can be used together and then attached to any hitch. This will keep a 4 Flat plug, like the Tekonsha # TK69FR from hanging down, but neither the Draw-Tite or Curt hitches have a pre-welded bracket for this.

With that being said, I recommend going with the Curt # C22UR. This assembled in America and is rated to 3,500 pounds towing and 350 pounds of tongue weight. It will also require no drilling to install, but there will be some trimming of an under-body panel to complete the install.
