2013 Toyota Sienna Replacement Trailer Wiring Harness Recommendation

Question:

Hi, I have a Curt hitch for my 2013 Toyota Sienna. The 4 pin wiring harness is connected to the rear lights of the vehicle. When I connect the trailer lights, the lights do not light. The hitch is a few years old, but I have hardly used it. I checked for ground at the Vehicle and trailer. Both are good. I checked 12 volts at the Vehicle connector with flashers on with a multitester and nothing. Do you have vehicle replacement wiring? Thanks

Thanks for reaching out!

We do have replacement trailer wiring for your 2013 Toyota Sienna and for that I recommend the Tekonsha T-One Vehicle Wiring Harness # 118498 because of how reliable it is.

If your current wiring has this same style where it pulls power directly from your Sienna battery via the power wire then I recommend checking to see if the fuse needs to be replaced before you replace the entire wiring harness. The fuse should be located in the engine bay near your battery.

Attached is an installation video of this wiring kit on a 2013 Sienna for you to check out.
