What Trailer Wiring Will Work For My 2020 Toyota Highlander

Updated 04/04/2022 | Published 04/02/2022

Question:

Would it be possible to purchase _just_ the vehicle harness from the Tekonsha TK99FR kit? I have the 4 flat plug already that I bought months ago from another retailer not realizing it wasnt going to work on its own even though I have the plug under my rear bumper. I need the internal harness to complete the wiring connections and nobody seems to sell just that piece. Hoping you can help. Thanks!

Though we do have the Tekonsha # TK99FR that will fit your 2020 Toyota Highlander, it is only offered as a complete harness

It's a quick and easily install that plugs directly into existing wire. The connection points are behind the trim panel near the driver's side rear seat belt bracket. The harness is constructed of 16-gauge bonded wire.

I have attached an installation video link below.
