FUEL SUPPLY CONNECTION
WARNING: THE FUEL RAIL AND/OR FUEL LINES ARE UNDER HIGH PRESSURE. USE EXTREME CAUTION WHEN DISCONNECTING ANY
FUEL LINE. QUICKLY COLLECT AND PROPERLY DISPOSE OF ANY EXCESS FUEL SPILLAGE
FACTORY “FUEL TEST-PORT”
1. Located on the fuel log (injector rail) is a “test port” fitting used by mechanics for checking fuel
pressures. This is usually covered by a
black plastic cap and is where the fuel solenoid feed line will be connected. Note: Care should be taken to be certain the port you
have selected is the “Fuel Test-Port”. Many late model cars have several similar ports that do not contain fuel. Remove the protective cap
from the test port fit ting. Note: Most Fords will require the entire test port connector fitting to be removed and replaced by the
supplied fuel log fitting. Check thread compatibility with AN fitting on main fuel line. (See Illustration C).
1. Now connect the 18-inch red fuel line from the fuel supply to the inlet side of the fuel solenoid.

ELECTRICAL HOOK-UP
1. Mount the toggle (Arming) switch in a location that is within easy reach of and in plain sight of the diver.
2. Using 18-ga. Blue wire and connectors supplied in the switch kit, connect a HOT lead (12 VDC POSITIVE) to the “Power” terminal of
the toggle switch. (Use 5 amp inline fuse if desired). This power source must be controlled by the ignition switch (See wiring
Schematic).
3. Connect a grounded wire to the “Ground” terminal of the toggle.
4. The system is furnished with a universal wide- open throttle switch. This WOT micro-switch is designed to work with the universal
mounting bracket. It’s maximum capacity is 10 AMPS and should only be used to activate low amp draw accessories or in conjunction
with a relay.
A. 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.
B. The mounting bracket is made of easily bendable material and may be formed to any configuration that will allow it to place the WOT
switch in the proper location.
C. 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. 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.
5. Using the 18-ga. wire supplied with the system, connect the remaining wide-open throttle terminal to the “Red” wire on the supplied heavy
duty relay. (See wiring diagram).
6. Use the red 12-ga. wire to connect the “BAT” terminal of the alternator or to the + post on the vehicle battery, to the “Black” wire on the heavy
duty relay. (If desired a 40 amp fuse may be installed here)
7. Attach one wire from each of the solenoids to the “Green” wire on the relay. Note: These coils are direct current and it does not matter which
wire is used. Now attach the two remaining solenoid wires to a good ground.
8. Attach the “White” wire from the relay to the fuel safety switch (PN 15708) terminal marked NO. Using the 18 ga. blue wire, attach the other
terminal on the safety switch marked (C) to ground. (See wiring Schematic) Note: If a fuel safety switch is not used simply attach the “White”
wire on the relay to ground.
9. Reconnect the battery cable.
10. At this point both solenoids should be tested for proper operation. Note: (Be sure the nitrous bottle is off and there is no pressure in the N2O
supply line). If you are using a fuel safety pressure switch you must use a jumper wire between the NO and C terminals when testing the
solenoids. 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 solenoids open. IMPORTANT: Make sure that both of the solenoids are clicking! If no sound is heard or
only one of the solenoids is working, 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 nitrous side of the system for leaks and retighten fittings if
necessary. With no leaks detected, start the engine and thoroughly check the fuel connections for leaks. Do not attempt to start engine if
nitrous has been accidently injected into the intake manifold. Disconnect the coil wire and crank the engine several revolutions with the
throttle wide open to clear the engine of all nitrous before attempting to start engine.
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.
