Install Video Guide for Routing Power Wire of Tekonsha Trailer Wiring Harness on 2014 Toyota Sienna

Updated 08/12/2019 | Published 08/11/2019

Question:

I read many of the reviews and a few folks had routed the wire along the interior of the passenger side. But i didnt see any recommended steps to get by the doors and then to the back of the glove box, and then finally into the and through the engine bay to the battery. Can you provide some guidance?

We've only ever installed the T-One Vehicle Wiring Harness with 4-Pole Flat Trailer Connector # 118498 underneath the bottom of the vehicle since that's what the install instructions recommend. I attached an install video that would walk you through that entire process which really isn't too bad. It more or less comes down to just avoiding moving parts and hot components.

I am sure running the wiring through the interior is possible but we don't have a way to really recommend that.
