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
plas
tic 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
com
patibility 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.
ILLUSTRATION C
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”
termi
nal 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.
