Question:
where is the control panel feed connection to plug in my after market Curt brake controller for an F10 2.7 lariat? I have torn into the panels and cant find the correct type of plug.

Hey Clay, according to my research the plug location for a trailer brake controller is located on the left side of the steering wheel near the floor. You can see one of our techs Connor showing this and plugging in the harness at the 7:00 mark in the video I attached.
If you have any other questions, please feel free to drop a comment and let me know!
