How To Choose Correct Trailer Wiring Harness for a 2017 Toyota Sienna


Whats the difference between the two light kits for the 2017 Toyota Sienna. Why would you choose one over the other?


Helpful Expert Reply:

There are several trailer wiring harness options for a 2017 Toyota Sienna. The first thing you need to do to find the correct one is identify the trim package, if it's an SE then this will further narrow down the selection as there are harnesses specific to this package. The next thing you will need to do is determine what type of trailer connector you need, 4-way is most common but there are also 7-way options for trailers with brakes. With all that in mind, there are multiple options for different manufacturers in each of these categories. For a non SE model that just requires a standard 4-way, I recommend the T-One Vehicle Wiring Harness with 4-Pole Flat Trailer Connector part # 118648 as our most reliable option.

If you have another setup not listed above please let me know what that is so I can help you pick out the correct harness.
