Curt T-Connector Vehicle Wiring Harness for Factory Tow Package - 4-Pole Flat Trailer Connector

Question:

I added a Toyota trailer hitch on my Highlander when purchasing, but not the wiring. Therefore, I am not sure what I really got and what I need. I keep seeing something about a converter under the dash with the factory installed tow option,inch but dont know how to confirm. I usually use a cargo basket, but would like the option to borrow a simple utility trailer on rare occasion. What will allow me to pull a plain jane utility trailer with taillights? Thanks!

I am happy to help you determine if your 2018 Toyota Highlander has a tow package or not. The easiest way is to visually inspect your vehicle on your own. If you take a look at the video for part # 118449 that I attached on a 2018 Toyota Highlander without a tow package he removes the back tray in the rear cargo area to find the plugs he needs to plug the wiring harness into. If you remove the cargo area tray and you have two plugs (one for a converter and one for the wiring harness) then you do not have a tow package and need part # 118449.

If you take a look at the video I have attached for part # 56042 for the 2018 Toyota Highlander with a factory tow package, he removes the cargo rear tray and there is only one plug to plug the harness into. If you find one plug, your Highlander has a tow package and you need part # 56042.
