I have a ZEX wet kit pretty much complete ready to go. It used to be that brain box kit that tapped into your TPS sensor but I got fed up and yanked the solenoids out and hooked it up the conventional style on a switch. Here is a list of what is included for $200 firm:

Fuel solenoid
Nitrous Solenoid
10lb bottle w/brackets
Heater blanket
Liquid filled pressure guage on bottle
Main nitrous feed line from bottle to solenoid
Two lines from solenoids to nozzle
Wet spray nozzle
Baggie full of jets from a 50-150 shot combo
Basic radioshack arming switch
Momentary activating switch
and I think thats it.......

Not included which you may want:
Micro switch
New wiring since whats included was for my previous vehicle and may not fit yours.

Pictures avail soon....

Thanks!
