Question:

My sienna has 3 and 4 pin connections to the tail lights and the kit only has 2 pin connectors. The site guaranteed a fit. None of the connections fit. Do you have adapters?

The Curt T-Connector Vehicle Wiring Harness part # C56106 is a fit for a 2017 Toyota Sienna but only if you have the SE model. If you do not have an SE model then you will want to use the Curt T-Connector Vehicle Wiring Harness part # C56261 instead. It sounds like you may have gotten the wrong harness as the Curt T-Connector Vehicle Wiring Harness part # C56261 uses a three and four pin connector on the driver side and a four pin connector on the passenger side. Whereas the Curt T-Connector Vehicle Wiring Harness part # C56106 uses a eight and two pin connector on the driver side and a two pin connector on the passenger side. There would have been prompts on the product page after you entered your vehicle info that asked whether or not you have an SE model before looking at the available wiring harnesses for that vehicle.

Unfortunately, there is not an adapter that will allow you to use the SE harness or a non SE model. I strongly recommend you reach out to the dealer with your VIN to see whether or not you have the SE model. I have attached an install video of the Curt T-Connector Vehicle Wiring Harness part # C56261 for you.
