Hey John, thanks for reaching out! How's the Curt Trailer Hitch Receiver # C13343 holding up for you?
I recommend picking up the T-One Vehicle Wiring Harness # 118648 simply because it's the most reliable kit we offer for your 2017 Sienna. It would also be a good idea to grab the mounting brackets # 18144 and # 18136 so the 4-Way is easily accessible next to your hitch receiver.
Do you already have a ball mount for towing?
