Nitrous Express DIESEL STACKER NITROUS NXD12000 - Manual (Page 3)

A. The WOT Switch must be mounted inside the vehicle using the accelerator pedal to activate the
nitrous system.
B. Assemble the micro-switch on the mounting bracket using the supplied
3⁄4” 4-40 bolts and nuts.
The switch can be mounted in several different configurations, select the position you require
and tighten the bolts. Do not over-tighten; the plastic micro switch can be damaged.
C. The mounting bracket is made of easily bend- able material and may be formed to any con-
figuration that will allow it to place the WOT switch in the proper location.
D. The activation arm on the micro-switch is extra-long. This allows you to twist, bend, or cut it to aid
in the ease of installation
5. Attach an 18-ga. jumper wire from the remaining terminal “ACC” of the toggle switch to one of the
terminals on the wide open throttle switch.
6. Using the 18-ga. wire supplied with the system, connect the remaining wide-open throttle terminal to
the one of the solenoid wires. (See wiring diagram).
8. Attach the remaining solenoid wire to ground.
9. Reconnect the battery cable.
10. At this point the solenoid should be tested for proper operation. Note: (Be sure the nitrous bottle is off
and there is no pressure in the N2O supply line). To test, turn the “arming” toggle switch to the ON
position and push the “activating” wide- open throttle switch. A clicking sound should be heard as the
solenoid opens. IMPORTANT: Make sure that the solenoid is clicking! If no sound is heard, check all
wire connections and the wiring schematic for proper connections.
11. With all components mounted, feed line and electrical connections completed, connect the nitrous
supply line to the bottle and FULLY open the bottle valve and carefully check connections on the
system for leaks and retighten fittings if necessary.
12. After a complete check and verification of all components of the system for proper installation and
operation it is time to have some fun.
Note: The nitrous solenoid is rated only for intermittent duty. Do not engage this solenoid for more than
20 continuous seconds. Solenoids that have “burned or scorched” electro-magnets will not be replaced
under warranty.
