Factory Tow Package Connection Point to Install Trailer Wiring on a 2005 Toyota Highlander

Updated 04/23/2014 | Published 04/22/2014

Question:

The manual that came with the car says this vehicle comes with a wire harness, but I cant find it am I missing something? I need a 4 flat connector for my trailer, but how do I know which one I need?

If your 2005 Toyota Highlander came with the factory tow package then the factory connection point to add a 4-Way will be located behind the driver side interior trim panel in the rear cargo area of the vehicle. You would then use wiring harness # 118248. I have linked a video showing installation and a link to the instructions for you.

If that connector is not present on your Highlander then you will need to use harness # 118413. This wiring harness just plugs in line with the vehicle tail light wiring. I have included a link to a video installation and the instructions for this harness as well.
