Parts Needed To Install Curt Echo On 2017 Toyota Highlander

Question:

Hello on my 2017 Toyota Highlander I’m trying to install the CURT 56217 Vehicle Custom 4-Pin Trailer Wiring Harness and CURT 57672 Dual-Output 4-Way Flat Vehicle-Side to 7-Way RV Blade Trailer Wiring Adapter so I can use the CURT 51180 Echo Mobile Electric Trailer Brake Controller to pull an RV. Do I still need to connect the blue, yellow and black wires for it to function properly? If so what else would I need to complete? Thanks

In order to use the Curt Echo Wireless Trailer Brake Controller part # C51180 on a 2017 Toyota Highlander you'll need the Curt T-Connector Vehicle Wiring Harness with 4-Pole Flat Trailer Connector part # C56217 but I recommend using the 4 to 7-Way with 4-Way Adapter part # ETBC7L. The 4 to 7-Way with 4-Way Adapter was designed for the Curt Echo. You'll only need to hook up the black power wire, white ground wire, and two 4-ways to one another.
