brake controller plug

ok, I've searched the forum and got a pretty good bit of help. but I still can't locate the plug. I'm assuming it's not plugged into anything. but I can't find any plug that is the same shape that is not plugged into something. I've untaped 3 plugs that are capped off, but they are the wrong shape. I kn ow I'm looking in the right area, 2013 tacoma with the true tow package. I even have the factory pigtail package with instructions in the glovebox.

 

Where are you looking? From what I know, it's down near the fuse panel somewhere. I have never actually looked though.

 

I finally found it. It was near the top of the firewall. Behind the connector with the foam wrapped around it , taped to the backside of a wiring harness. Damn near impossible to get to.
