2024 Toyota Grand Highlander Trailer Wiring Harness for No Factory Tow Package

Question:

Looking for trailer wiring harness for 2024 toyota grand highlander w/o prewired tow package. Dealer was no help. I see the 10 pin connecter under the left rear passenger cup holder. What part connects that to the plug for the trailer?

Since your 2024 Toyota Grand Highlander doesn't come with the factory tow package you need the Curt T-Connector Vehicle Wiring Harness # C79VV. The module plugs into that 10-Pin connector you found under the cup holder and then the 4-Way harness connects to the plug found under the driver-side rear bumper section. There will be a dust cover you need to remove prior to plugging the 4-Way harness into this connector.
