Electric fuel pump wiring?

You could always add in the two systems so it can shut off aether way.

There is also the impact sensor that can be used to shut off fuel. Though you need a reliable one and probably more then one. Front/Back or a central located sensor. The ole 2 wire airbag sensor could be modified to control fuel since it detects an impact. I am really thinking more and more on this type of shutoff because some people have had issues with oil switches if they get a switch that shuts off fuel at a higher oil pressure rating then the required switch settings. They roll up to a light with a quart low of oil and engine shuts off. Our trucks, well atleast mine is getting older and oil pressure is not on viagra anymore, so it does drop lower then normal. I am though going to try the oil switch first, but if it causes a problem I am definitely going towards an impact/roll over sensor.

The oil pressure switch only needs 5 psi to switch, so if you are dropping below that at a stop, you got problems. Also make sure the oil pressire switch has a large hole in it so it doesn't clog from an errant piece of sludge. Use a switch like this: http://www.ebay.com/itm/310333238965...t_12655wt_1327

I'd just do the wiring based on that website you linked. It seems to be a lot easier diagram to follow. Just add a T to where the original sensor was so you can put the old dummy light sensor and the new switch in place right there and wire like this

Just hooked my own up followed this diagram. Worked fine on the first try. Tried following the other diagrams and they weren't dumbed down enough for me. Either way, works!
