The trailer wiring harness I recommend for a 2020 Toyota Sienna XLE is the T-One Vehicle Wiring Harness part # 118648 as it is a plug-n-play fit and our most reliable option. That said, this harness only has a 4-way but that's all that is available for this vehicle. However, you can convert this to a 7-way using the 7-Way RV Upgrade Kit for Trailer Brake Controller Installation part # ETBC7L which comes with both 4 and 7-way connection points. Please note, if the trailer has brakes then you'll want to use the Curt Echo Wireless Trailer Brake Controller part # C51180 which is designed for the exact adapter above because it's wireless so far less work/parts are involved for installation.

In regards to mounting, you'll also need the Curt No-Drill Bracket for 6-Way or 7-Way Round Trailer Connector Mounting Brackets part # C57202. If you have the Draw-Tite Max-Frame Trailer Hitch Receiver part # 76112 this won't be needed.
