Recommended Trailer Wiring Harness For A 2018 Toyota Sienna

Question:

Hi, I am wondering if it is possible to use/install this on a Sienna that did NOT come with the factory tow package? All I have is a hitch installed. I need to tow a Casita travel trailer! Thanks so much!

When it comes to installing a trailer wiring harness on your 2018 Toyota Sienna I would recommend The Tekonsha OEM Replacement Vehicle Wiring Harness w Brake Controller Adapter - 7 Way Trailer Connector # TK87FR.

This harness will give you the factory OEM harness. This custom connector end plugs into the built-in port beneath the dash of your vehicle, and the other end plugs into the back of the Tekonsha P2 # 90885.

The T-One connects quickly and easily, it plugs into the connection points behind the tail lights, and then you run the body harness up to the car battery.
