The RR kit has this aluminum piece that mounts with 2 screws under the dash. It was rubbing on the underside of the dash and against the side panels. The only reason I can see for keeping it on there is my power outlet is mounted to it. I will be moving the power outlet and removing this piece of aluminum. The 2 mounting holes are next to my thumb. It was rubbing at the top where you see the bare aluminum.
Another picture. I will put more up when its back together. I put the orange gas line on the bottom of the dash to keep it from rubbing. didn't work as you can see. I was also adjusting the sensitivity of the pickup on the TrailTech tach so i get a correct reading.
