Parts Needed To Tow a Trailer with Electric Brakes with a 2018 Toyota Sienna

Question

Question:

Hello, I drive a 2018 Toyota Sienna LE. Im looking into purchasing a popup camper. The camper trailer is equipped with electric brakes and weighs approximately 1,800LBS dry. I was wondering what I need to completely install the hitch, wiring harness, and brake controller if needed. A side question, is there a wiring harness that includes the brake controller? Thank you for your help,

I have everything you need to get setup and towing a trailer with brakes using a 2018 Toyota Sienna. The first thing you'll want to start with is a trailer hitch, the etrailer Trailer Hitch Receiver part # e98853 is what I recommend. Then for the trailer wiring harness, I recommend the T-One Vehicle Wiring Harness part # 118648 which is plug-n-play. Once you have the 4-way you can then adapt this to a 7-way using the 7-Way RV Upgrade Kit for Trailer Brake Controller Installation part # ETBC7L which pairs perfectly with the Curt Echo Wireless Trailer Brake Controller part # C51180. The Curt Echo is what I strongly recommend using since it's the only option which would not require splicing into the vehicle.

Unfortunately, the brake controller and wiring harness much be purchased separate.
