I want to make a kill switch which will kill the fuel pump but I don't know how to wire it. Does anyone know how to wire a cut-out and where the wires for the fuel pump are located? Thanks,

Why another switch, there is already a fuel cut off switch in the system, when you crash it cuts off the fuel. If it's for another reason please explain so we can help you more.

I want to wire a kill switch to stop/slow down wanna be thieves. After looking at a few threads, killing the fuel pump sounded like the best way to go.

You can locate the fuse that goes to the fuel pump and tap in there to wire a kill switch in . Make sure if you directly tap the fuse you keep a fuse inline in the system after your done . Best thing would be to tap in on the backside of the fuse panel or junction box under the hood depending on where your fuel pump fuse is located .

That doesn't sound too hard. Anyone else with any ideas/alternatives?

Heh , you could get into car alarms and wiring relays into it so in different modes would disarm the fuel system .
