Trailer Wiring Recommendation for a 2015 Toyota Sienna


I have a 2015 Sienna SE and Im interested in a Class 3 hitch with a four pin wiring connection run outside not run out the back hatch. Id also like to minimize cutting and splicing into the vehicles wiring harness. What are my options? Thanks.

For trailer wiring for your 2015 Toyota Sienna SE you would want the Tow Ready wiring harness part # 118498 as it has been confirmed to fit your vehicle.

Having the 4-way run out of the back hatch is actually the preferred method although it seems like it wouldn't be. Having the 4-way stored inside the cab of the keeps it protected from rain and moisture to prevent corrosion and keeps it protected from damage to the wiring or connector by rocks or debris that might be on the highway.

For a Class III hitch you would want the part # 75237.
