As Mark explained to me, the sensor measures the position of the seat and how hard the airbag deploys as a result. I unscrewed the fasteners and removed it, attached under the seat on the cushion rods with wire tie, very secure and will work .. it's not exact as stock, but my seat is always as far back as possible so no concern about airbag inflation.
You know I literally finished the install of the rails and then thought, shoot, I should have done pics or a vid since the instructions are kinda weak, I don't know why I didn't think of it when I started, I guess I was on a mission to just get it done and didn't think. I can take some shots as it is now, I've test the fit but took both seats out still for the rollbar install.
