Just signed for a 2022 LE AWD to cart around our brood and tow a little fiberglass camper we have. Won’t have to worry about kick sensor because the LE doesn’t have it! Vehicle should be arriving in about a month, and trying to get a jump start on hitch/wiring harness install - thanks to all who shared in this thread. I don’t trust myself enough to deconstruct the rear end of the vehicle and install myself, so will plan for local shop to do the work. I’m trying to find all the materials that will be needed for the install so I can hit the ground running when I get the vehicle. I’m planning for the eco hitch because it looks so much better, is stainless steel and provides better ground clearance. I will need a 7-pin connector, which looks to be one of the trickier parts on this install. So far, my supply list includes:
Hitch
2021-2022 Toyota Sienna - ONLY trailer hitch that does NOT block kick sensor – with Stainless Steel receiver
OEM wiring harness (thanks Bmac13)

Bracket

Does this look like a complete list?
I am concerned about where the bracket for the 7-way pin will be mounted and have yet to see a solution here.
I also have a P3 brake controller from my prior vehicle that I could transplant, but I’m a little concerned about installing it in a complex vehicle like the sienna and all the necessary wiring this will entail (I did it in my very analog Outback and the cruise stopped working and I couldn’t ever figure out how to fix it, I can only imagine what might happen in a new sienna!). Do any of y’all have experience with wired brake controllers in the gen 4 sienna and/or wireless brake controllers? I’d prefer to use my wired P3 since I’m used to it and already have it, but don’t want to have to mess with a bunch of wiring in the dash, so might be forced to use a wireless controller.
We can’t wait to take delivery and go on our first camping trip. Thanks for sharing/helping!
