I have a 2021 Toyota Highlander and want to mount a hitch and a 4-way wiring harness. I know these harnesses route to the outside so what is the best hitch for my vehicle to be able to EASILY mount the 4-way?

Expert Reply:

For your 2021 Toyota Highlander Curt Trailer Hitch Receiver # C45CR is because it has a high towing and tongue
weight capacities and cab be used with a weight distribution system if needed.

The correct 4-way trailer wiring harness for your 2021 Highlander will depend on if you have the factory tow package or not. If you DO have the factory tow package you need the T-One Vehicle Wiring Harness for Factory Tow Package # TK74FR.

If you DO NOT have the factory tow package you need the Curt T-Connector Vehicle Wiring Harness # C76CR.

To attach either of these harnesses to the hitch you simply need the Mounting Bracket 4-Pole Flat # 18144.
