on the relay there will be male spade connectors sticking up with numbers next to them, the numbers I put are where you'll be connecting the wires too
you'll need female speed connectors to connect the wires to the relay

after you locate and cut the fuel pump wire
there will be 2 sides to it
-pin 87 will go to the wire leading to the fuel pump
-pin 30 will go to the other side of that cut wire
-pin 85 you will connect a wire to it and then ground it to the chassis
-pin 86 you will get 12 volts, from your battery or any other source you want to find and put a toggle switch on it to turn it on and off

this will power the relay and make the fuel pump wire one again, think of it as an on and off switch

this will tell you about relays and what they look like

apocolypse: Is the cutoff easy to do or pretty hard. Can I have a shop do it for me or is it better of to do it myself. Also how many switches do you recommend and where to place them? Thanks man, sounds like you know your stuff.

it isn't to hard to do, you jsut have to locate your wires
you can put as many switches as you want in there
I used to use a positive switching switch that was already in the car
like a 350z I did, you had to press the cruise control button and have your seatbelt on before the car would start

I used to charge around 75 dollers to install them, I'd assume any shop would charge around the same
