Installation Notes and Tips

Verify the vehicle year and model before ordering. This actuator is listed for 2011-2019 Toyota Sienna applications and uses a 3-terminal, male connector layout with 3 mounting holes. Compare the original connector, mounting points, and actuator shape to confirm a proper match before installation.

Because no wiring harness or actuator arm is included, reuse the existing related components when they are in serviceable condition. Inspect the liftgate latch, linkage, and electrical connector for wear or damage during replacement to help ensure proper operation after installation.
