Parts Needed To Add 7-way Connector And Trailer Brake Controller To 2021 Toyota Sienna  


Hello, Im trying to figure out a towing setup for a 2021 Toyota Sienna. I found the hitch and a wiring kit, but I also need a brake controller and a 7-pin setup. Can somebody help me figure this out? Thank you!

I would be happy to recommend everything you will need to add a 7-way connector and trailer brake controller to your new 2021 Toyota Sienna.

First you will need to have a 4-way connector installed of which I recommend the Curt Powered Tail Light Converter with 4-Pole Flat Trailer Connector # C59236.

With a 4-way connector installed there are two different 7-way connector options.

The first is the # ETBC7 with a traditional trailer brake controller like the Tekonsha Prodigy P3 # 90195.

The option I recommend is the # ETBC7L with the Curt Echo Wireless Trailer Brake Controller # C51180. The reason for this is that since the # C51180 plugs directly into the 7-way connector you will not need to run any wires inside of the passenger compartment of your vehicle, and will not need to drill any holes in your dash to mount the controller.

The # ETBC7L will install very simply by plugging in to your newly installed 4-way connector and only requiring you to extend the black wire to the battery of your vehicle with the included 40 amp circuit breaker, and ground the white wire to the frame of your vehicle. You will also need No-Drill mounting bracket # 18140 to attach the # ETBC7L to your trailer hitch receiver.

For a trailer hitch receiver I recommend the Curt Trailer Hitch Receiver # C22UR as it is the only trailer hitch confirmed to fit your Sienna at this time.

I included videos for each of the products mentioned for you to take a look at.
