Welcome back, William!

On the driver side, you need to disconnect the center gray taillight socket, being careful not to break the locking tabs. Plug the T-Connector containing the yellow wire between these separated halves. Next, disconnect the top black taillight socket and plug the T-Connector containing the red wire between these halves. For the passenger side, you only need to connect to the center plug.

I also have a link included to an install video we have of the Tekonsha T-One 118426 being installed on a 2006 Escape for you to check out. It is identical to the Curt T-Connector # C56345 you purchased and installs the exact same way. I agree that the instructions aren't the greatest for this harness, so the video should get you squared away.

What are you going to be using this for once it's installed? Towing a trailer or a bike rack with lights?
