Anyone put in a Brake control in a 2nd Gen Tacoma with tow package?

[Chasing Trials]

I have a 2014 Tacoma PreRunner with the tow package, & see the 7 pin plug under the bumper. Since I think I read that the brake controller wire has been brought up to under the dash somewhere, & maybe some kind of a receiver plug for a controller? I don't know if someone has put up a photo of it here or not. To help me find it, or I have to order it?. Figure out if I can do it with a Tekonsha Prodigy P3. Sounds like if I call e-trailer to order they''ll help big time. I'm a "visual person" with nerve damage in right hand to go fishing around in tight places. But,no biggy, I can always wait til I call Et-trailer Monday, sounds like they are real helpful.
