Its not that hard, its the wire w/ 12 volts runnin through it when u turn the ignition on. Check the plug by the fuel pump, under the grey metal protective plate in the trunk.

If you're goin through the trouble of wiring a kill switch, run a fresh power lead to the fuel pump with a new dedicated relay because the stock relays don't like the current draw of the warlboro pumps and they can cause fuel starvation up top on big boy-HP cars.

If you need wiring diagrams:

if you want i can dig through my tool box and find the pin layout of the ECU. i have the layout for my 95, is it the same? By tapping in upfront you wont have to worry about running wires to the back.

btw, whats the point of a fuel cut off switch. isnt there one in the trunk incase the car rolls anyway?

kind of a security caution maybe? hidden switch so you can't start the car without turning it on. just a guess.

exactly. not that it has alot done to it, just with the new fast and furious coming out i gurantee they are going to get stolen left and right.
