How do I make a fuel pump cut-off?

Hey everyone, I'm wondering if anyone knows how to wire in an on/off switch for the fuel pump. I'm moving to the city and want an extra theft-deterrent. Thanks!
Btw it's an '89 Base 4.0L 5spd

Which city? I think Steve or Josh will have an answer for this one. I like the idea.

You can do either. I have one to turn it on past the 2 second start phase. To turn it off, just put the switch in the positive wire to the pump. On, it will act normally and off the pump will not work. Add a little wire and you can put it anywhere you want. Mine being on the dash

Cool, so are there wires going to the relay?

The hot wire from the relay in the poser distribution center goes to the fuel pump in the rear. You can access that wire off the really under the hood by the power distribution center or somewhere toward the back.
