The 10 pin connector you are looking for to install the Curt trailer wiring harness part # C56217 on your 2018 Lexus RX 350L is under the dash and not the rear cargo area you sent in a picture of which is maybe where the confusion stems from. I attached a picture that shows where you'll find the connector and what it looks like as well as a link to the install instructions and an install video.
