interesting question most people would already know the answer, well for starters most people just disconnect the all the spark plug wires, but if you really want to get all crazy about it pull the plugs to the injectors to, or you could pull the fuse for the ecm. or if you really want to go all out drain the gas out of the tank, pull all the fuses and jumper the starter, or you could pull the motor and transmission from the car and leave the starter connected and attach it to a battery.

I belive you disconnect the MPI fuse for the injectors and another for the spark so you don't accidently get a wicked shock.

VFAQ has all the steps and pictures bud. They have procedures with picutures for a huge array of DSM procedures.
