Parts Needed to Add a Trailer Hitch and 7-way Trailer Wiring Harness on a 2022 Toyota Sienna


I have a 2022 Toyota Sienna. I need a hitch and 7-way connector. Can you point me in the right direction for what all I need?

I can definitely get you set up with what you need for a trailer hitch and 7-way wiring harness on your 2022 Toyota Sienna. The first thing you will need is a trailer hitch, for that I recommend the Curt Trailer Hitch Receiver # C22UR. This hitch is made in the USA, has a bolt-on, no-drill installation and will provide you with a 2" receiver opening which is the most common size used for hitch mounted accessories such as ball mounts, bike racks and cargo carriers.

Next, you will need a 4-way wiring connector that will be adapted to become a 7-way. There is no 7-way you can get without first having a 4-way connector. If you do not already have a 4-way connector on your Sienna then I recommend the T-One Vehicle Wiring Harness # TK69FR. The T-One connector plugs into your vehicle's wiring harness, which is located in the rear cargo area. You will have to remove the plastic threshold cover, side panels, cargo trays, and interior trim panels to access this harness. Once you've plugged in the T-connector, run the hot lead up to your car battery. Connect the lead to the included fuse holder, and then connect the fuse holder to the positive terminal on your battery and insert the provided fuse.

You will then use the Universal Installation Kit for Trailer Brake Controller - 7-Way # ETBC7 to adapt your 4-way connector into a 7-way using the included parts in the # ETBC7. You will also want to pick up the Curt No-Drill Bracket # C57202 which will provide you with a mounting point for the 7-way bracket included in the # ETBC7 kit.

If you are needing trailer brake controller I recommend the Tekonsha Prodigy P3 Trailer Brake Controller # 90195.
