This is a Tekonsha Prodigy brake controller. The stock plastic snap-in bracket is great in this truck. It squeezes in the hole, then "snaps" in firmly behind the lip of the pocket. No screws, no worries. I drilled a 1" hole in the back of the pocket to pass through the wiring harness. Tekonsha makes an F150 plug so no need for wire splicing. The harness on my truck was just forward and above the diagnostic plug.
