Location Of Curt Wiring Harness Connections For a 2021 Lexus RX 350L Without Tow Package
Question:
Where is the 4-pin connectors located on a 2021 Lexus RX350L? I believe I have found the 10-pin connector on the rear driver side as shown in the picture. I cant find any 4-pin connector though. Neither the 10 or 4 pin connectors are under the cargo tray along the back end of the vehicle like they are shown in Highlander installation videos/instructions. The 2021 RX350L has air ducts routed in that area and there are no connectors on the wire harness under the those ducts. Please help find the 4-pin and verify thats the correct 10-pin. Thanks

For the Curt T-Connector Vehicle Wiring Harness # C56217 on your 2021 Lexus RX 350L the connectors will be located in a different spot. The 10 pin connector should be located on the passenger side just below the taillight.
The 4 pin connector will be underneath the drivers side bumper cover. It may require you to use the Curt T-Connector Vehicle Wiring Harness for Factory Tow Package # 56083 to make that connection. The video that I linked below will help you find the 4-pin connector.
