Question:
I have a 2019 Toyota Sienna XLE, that I need to setup to pull a very small travel trailer. Which wiring harness do I use to setup a 7 wire setup. I have a Curt Echo Wireless Brake Controller - 7-Way Plug Mount w/ Bluetooth App I can use.

Hey Paul,
To get to towing a small trailer with your 2019 Toyota Sienna I recommend the following:
- etrailer Trailer Hitch Receiver # e98853
- T-One Wiring # 118648
- Universal Upgrade Kit # ETBC7
- Mounting Bracket # 18136
I really like the etrailer hitch because it has a hidden crosstube and a matte black finish for better protection, and then the T-One and upgrade kit gives you a reliable wiring package with all of the parts needed so you can use your Curt Echo Controller # C51180.
