Should Trailer Wiring be Installed at Same Time as Draw-Tite Hitch For 2020 Toyota Sienna

Question:

I am planning to buy the Draw-Tite Max-Frame Trailer Hitch Receiver - Custom Fit - Class III - 2inch - 76112. I plan to use it on a 2020 sienna, and currently I am only going to use it for a bike rack. But I was wondering if I should plan to get and install trailer wiring at the same time, just in case I ever decide to pull a trailer. I have never installed either one, and I was wondering if it would make sense to do both at the same time. Or, perhaps the wiring can easily be done at another time. Any feedback would be helpful. Thanks!

Since you will already be installing the hitch, it makes sense to go ahead and install the 4-way wiring harness in your 2020 Toyota Sienna. The wiring can certainly be done at another time if you like, as the two installations won't overlap so it isn't necessary, but if you have an idea that you might be towing sometime soon, then I'd add the 4-way right now. If towing isn't something you aren't quite sure about, then it won't hurt to wait.

I'll go ahead and list out the hitch as well as the correct wiring harness fits, as there are different wiring harnesses depending on if your 2020 Toyota Sienna is an SE model or not (the hitch will be the same no matter the model, however):

- Draw-Tite Max-Frame Trailer Hitch Receiver # 76112

- Non-SE Model of 2020 Sienna: T-One Vehicle Wiring Harness # 118648

- SE Model of 2020 Sienna: T-One Vehicle Wiring Harness # 118498
