118824 is Tekonsha's part number for The T-One Vehicle Wiring Harness with 4-Pole Flat Trailer Connector # TK69FR. We do not currently have an installation video for this wiring harness, but I can certainly help you out with this process. The harness has a connector that will plug into the trailer light connector in the trunk of your 2021 Toyota sienna; you will likely need to remove the trim panels and side cover to gain access to this connector. You will then need to connect the white wire with the ring terminal to a bare metal spot on your vehicle; this will provide a ground connection. Lastly, you will need to run the 12v power cable that has the in-line fuse and connect it to the positive terminal on the battery. I have attached a photo of the instructions that will help you when installing the # TK69FR.

The only trailer hitch receiver that is currently available for your 2021 Toyota Sienna is the Curt Trailer Hitch Receiver - Custom Fit - Class III - 2" # C22UR, and this is not technically a hidden hitch. This offers a simple bolt-on installation process that does not require welding or drilling. We do not currently have installation videos of this receiver being installed on a 2021 Sienna. I have, however, attached pictures from the installation instructions along with a picture of the receiver installed on a Sienna.

I have a 2021 Sienna LE. I purchased a Tekonsha 118824. I'm having a heck of a time finding the 8 pin connector. Any ideas? the instructions are very vague

@Vince The connector is located behind the second row of seats, on the driver's side, on the wall. This is also where the OPTIONAL spare tire is located. Remove the panel, and spare tire if so equipped, and you will find the connector in the lower part of that area.
