This is a replacement mounting plate for the Superchips Trail Dash 2 programmer. Created for my 2017 Jeep Wrangler Rubicon, but applicable to anybody with one.

Plastic weld a flat phone magnet to the back of the plate.

If you have a set of grab bars for your Wrangler JK, here is a mount that I created to attach to it.
