OK, so just for peace of mind, I climbed under the dash today and inspected. Found this, which I am pretty sure is the gray trailer brake connector that Ford puts on their vehicles. (I had to install one last year on my 2018 Explorer and it looks like what I remember, but that was LAST year!) Anyone want to verify this for me? I really can't easily get at my Explorer. Taking apart the entire dash is not what I want to do today.
