Recommended Wiring Harness for a 2015 Toyota Sienna

Question

Question:

Hello, First off Ive been so satisfied over the years with my hitch purchases from etrailer. Everything is usually a perfect fit. However, my recent purchase of a hitch and 4-flat wiring harness for our 2015 Toyota Sienna doesnt seem to be correct. The hitch was perfect. The wiring harness connectors, however, do not match my taillight connectors. Whats the next best step for me to get the right wiring harness kit? Thanks

If the Hopkins # HM11143495 isn't matching the plugs on you 2015 Sienna, it may be due to this only fitting the SE trim package. If you do not have the SE trim package, you will need the # HM43494. That being said, I did include pictures of the plugs for you to double check and make sure they do match.
