Designed for a 2022 Toyota Tacoma, not sure if it'll fit on any older models.
Mounting bracket securely pops into the screw holes on the top of the metal mount that comes standard with the Prodigy P2, enabling easy removal and replacement with no screws required. Bracket itself clings to the little notch where the tire pressure set button is located, just at the lower part of the left-hand side of the dash.
1st iteration of this design, definitely room for improvement. It hangs down is a reasonably kick-able location, but it's better than nothing for this super specific use case. I'm sure somebody could modify it to fit other brake controllers if they felt like it.
Also the screw design isn't mine, I downloaded it a while back and didn't keep track of the author, but it ended up being useful for this design - apologies to its author.
