Question:
Hi all! 118498 seems to be listed on your webpage as fitting the non-SEinch models of the Toyota Sienna see pic, but the QandA says that it doesnt fit. Which is right?

Hello Jason, thanks for reaching out. The Tekonsha # 118498 will fit all models of the 2013 Toyota Sienna. It was only after 2015 that Toyota added different plugs for the SE models. I can see how the way we have it listed is a bit confusing. Basically it says the # 118498 wiring harness will fit both the SE and non-SE models. I used to have a 2013 Sienna XLE (great van by the way) and it used the same wiring harness as the base SE and base models. I also triple checked with the manufacturer and they confirm the # 118498 is for all models of the 2013 Sienna. Sorry for any confusion and feel free to comment below if you have any questions or need anything else.
