Sam,
Here are some pics of my setup. Only had her a couple months. Notice I did say I assumed it was factory.......
I'll have to look at it closer to see if there's a wire somewhere just hanging out. The shutoff works great. A lot better than the throttle shutoff on my other smokers. After looking at the pics again, if you look at the last pic, just left of the fuel filter, it looks like an unused plug. Prolly for the missing electric solenoid.
