If you don't already own one, go pick up a Chilton's and/or Haynes manual. There are wiring diagrams in the back (pg. 12-22 in the Haynes) that will tell you where they are wired. You'll need the manual for other things as well.

should be a relay under the hood, it has an orang wire coming out of it. That's the original fuel pump relay.
