Fuel pump relay location

Thanks for the replies. I got the Summit fuel pump relay kit. Has good directions. I just wasn't sure about location. I will find a weather resistant location, and I plan on wiring it through the oil pressure sending unit. I might have to order the one from summit. It comes with a circuit breaker, and I plan to use a fuse and switch to the 12v switched wire. I plan on using an inertia switch. Does it get wired into the wire to the pump, ground, or where?
