For a 4-way wiring harness for your 2022 Toyota Highlander Platinum Hybrid without the tow package you need the T-One Vehicle Wiring Harness with 4-Pole Flat Trailer Connector # TK99FR. When it comes to wiring, we have found Tekonsha to be the most reliable. This wiring harness plugs in to the connection point in the rear of your vehicle and will provide you with a 4-way connection to power your trailer's signal lights.

I have attached an installation video for your reference.

Link to the video? My hybrid has something plugged into the side location, and does not seem to be a towing package. Is there a rear location? Where?

@JasonF the video link is down below, you have to scroll down a little bit. The written instructions are linked below as well. The # TK99FR product page also has more installation videos if you want to check those out. The vehicle’s 10-Pin tow plug is located on the driver’s side behind the trim panel near the rear seat belt bracket/coil.

@RobinH I dig deeper in the side and found an open connection. Can remove my question of it causes more confusion. Thanks!
