Will Hopkins Wiring Harness for 2017 Toyota Highlander Work With or Without Tow Package

Updated 04/18/2023 | Published 04/16/2023

Question:

Is there any harm in installing the powered converter if my vehicle has a tow package? It is difficult to determine on my 2017 Highlander. There are many, not so clear, ideas from forums on whether it has or not.

In my experience, most Toyota Highlander's don't have the factory tow package and need both the trailer connector and converter like what comes with the Hopkins Plug-In Simple Vehicle Wiring Harness with 4-Pole Flat Trailer Connector part # HM11141845. If you did in fact have the factory tow package, you would simply only use the trailer connector as there would already be a harness plugged into the spot for the converter. If you want, you can use the install instructions for this product attached below to see if you already have a converter where that section goes and in which case that would mean you do have the factory tow package. That said, if you don't know and don't want to go through the trouble of removing panels twice you can order the kit for models without the factory tow package and use it either way. It won't hurt or harm anything, you'd just have an extra harness/converter that wouldn't be used.
