Review on Efficient Replacement Part: Tekonsha P3 Mounting Kit for Enhanced Performance by Jeff Apel

The brake controller that comes with this mount is great but they should have spent more time designing the mount. Specifically how to install it on a car. When the two pieces are connected, the bracket blocks access to the screws that attach it to the vehicle. If you install this part first, you won't be able to find a screwdriver next to it to tighten the screws that hold the two parts of the bracket together. You will need to use needle nose pliers to tighten them.
