I purchased the bezel kit from the dealer, and it didn't have the template. It did have extra plastic pin things for the bumper though.
Once I got the bumper off, I hit the underside with a rag and water, and was able to see the guide marks for cutting. Used a rotozip to cut it out, and that left some raised areas from the heat, but I wasn't concerned with that. Drilled holes in the guide marks. All is well.
