By the PCM there is a connector that isn't hooked up to anything. Its for making the fuel pump kick on to drain the tank.

Hole in the bottom of the tank, works really well. A sawzall can do the job. Seen it done once. 10 gallons gone in about 60 secs.

If you pop the hood, while looking at the engine its in the upper passenger side. Its a black box with all the harnesses running to it. You will look around and see a connector that isn't hooked up. It will allow you to power the fuel pump.
