Question:

Hello, We are looking to purchase a hitch and wiring kit for our 2015 Toyota Sienna XLE. Our vehicle has the tow prep kit and was told there is a power wire already running to the back. Have you heard of this? Where is this wire located? What wiring kit do we need?

Expert Reply:

If there is indeed a power wire already ran, it would terminate in the cargo area of the van, most likely in the spare tire or jack storage compartment. The other end would terminate in the engine compartment near the battery or the fuse box. Both ends of the wire would likely have a label or tag on them for identification.

I checked with my trailer wiring brain trust at Curt and Tow Ready, and they haven't heard of this option. Both the Curt # C56261 and the Tow Ready # 118648 include a wire that's intended to run from the converter box to the battery, with the yellow fuse holder installed inline. The two harnesses serve the same function and would install in the same manner. I'd choose the Tow Ready # 118648 as it's a bit less expensive.

I've linked you to our FAQ article that explains how to route the power wire.

The # C56106 harness you mentioned is designed for use on Sienna SE models only. It wouldn't work on your XLE model.
