1st step: Go down to your local feed store or who ever would carry this stuff-two wire taps, and about 10 feet of electrical wire, and a switch (like an on off switch so you can close the circuit to make it smoke and open, or disconect the circuit to turn off the smoke).
2nd step: I got the two taps and tapped into the Pink and yellow map sensor wires. I then took the wire that i had and cut it into two equal lenghts, hook one end of each wire upto the switch and then run one end of one wire to the pink tapped map sensor wire and the other to the yellow tapped map sensor wire.
Next just find a place to mount your switch in ur truck.
I hope that this will help you out, it worked good for me. I think that the map sensor wires should be the same on the 98' as the 00' but idk.
