Quickly and easily install a 4-way trailer connector on your vehicle with this custom harness. Connector plugs directly into OEM tow package port - no cutting, splicing or tapping required.
Features:
Installation
This custom-fit T-connector plugs into your vehicle's factory tow package wiring harness, which is located behind the driver's-side interior trim panel in your rear cargo area.
Once installation is complete, the 4-way connector will be stowed in an out-of-the-way location within your cargo area.
It is recommended that you use a small amount of grease on all electrical connections - the plug on your automobile and the 4-pole connector itself - to help prevent corrosion.

We are very happy with our trailer hitch, and all the accoutrements that we purchased with it. Your videos were enormously helpful, the hitch went on easily with a bit of help from our teenage daughter to lift it up into place, and we recommend your business to friends when they express an interest in getting a camper.

It sounds like your 2012 Toyota Highlander didnt come with the factory tow package and that you would have needed part # C56217. It includes the additional wiring component that installs under the dash to complete towing circuit.

Still working. I installed it and store in the area under the back mat. I believe thats the best because its not exposed to the weather. Id buy it again if needed as I saved a ton of $$ by doing it myself.

I'll make that happen for you Steve. The 56042 is a fit for 2008-2019 Toyota Highlander models equipped with the factory tow package.
