Help wiring fuel pump cut off switch...

[MikeR351w]

I have a 93 LX 5.0 hatch. I want to wire in a cut off switch to the fuel pump relay. I bought a 30amp switch which has three prongs. Is this switch rated at 30amps, too high or too low for the power that will run through it. Also, do I ground it or just run both hot wires to the different sides of the switch? Should I just get a two prong switch????? I park my beast in the city and dont want it stolen! Help!

I dont want any electrical fires...

Lets do this the easiest way possible. And safest. Use the switch to control the relay ground. Not the 12v to it.

HEY MAN.I DONE SOMETHING SIMILAR TO MY STANG WHICH WORKED WELL AS AN ANTI-THEFT DEVICE.I BOUGHT A TOGGLE SWITCH WITH TWO PRONGS,MOUNTED IT BETWEEN THE BACK SEAT-ON THE SIDE OF THE SEAT NOT THE BACK,AND THE PLASTIC TRIM.ITS EASY TO GET TO AND ALMOST COMPLETELY INVISIBLE DEPENDING ON HOW LOW YOU MOUNT IT.I RAN TWO WIRES FROM THE TOGGLE SWITCH BACK TO THE HATCH AREA AND CONNECTED IT TO THE INERTIA/SAFETY SWITCH.HOPE THIS HELPS.

Ran a two way switch with three prongs. Hid it under the dash. It is awesome! Only cost $5.00! Cheapest anti-theft system ever. I am considering disabling the ignition too.....
