How to install the T-One Vehicle Harness with 4-Pole Flat Trailer Connector 118255

Question

Question:

I have a 2015 Lexus RX 350. I’ve contacted the dealer and my vehicle does not come with the factory towing package. It does include the additional pigtail at the back bumper on the driver side but it does not have power on it. I recently contact you all as to which wiring harness I should get and y’all suggested the T-One Vehicle Wiring Harness with 4-Pole Flat Trailer Connector - 118255. Based on the instructions and pictures, I’m not 100 certain on how to connect it. Can you all provide further instructions or a video guide on how to install it please? Thank you for all your help!
