Nitrous Express Proton Nitrous Systems - Manual (Page 2)

4. After installing the jets into the nozzle using the supplied
red (Fuel) and blue (nitrous) hoses, connect the Nitrous/
Fuel Management System to the nozzle, paying attention
to connect the Nitrous outlet port to the fitting labeled
Nitrous on the nozzle and the Fuel outlet port to the
fitting labeled Fuel
5. Using a backup wrench, connect the previously cleaned
supply line to the Nitrous Inlet port and tighten securely.
NOTE: ALL HOSES MUST BE INSTALLED WITH A
BACKUP WRENCH ON SOLENOIDS!
Plumbing the Fuel
1. Locate the factory supply line connecting the fuel
filter to the EFI fuel rail. This line must be cut and a
Tee inserted to supply fuel to the nitrous system. Use
extreme caution; this line contains flammable fuel
under high pressure. Carefully cut this line and insert
the Tee fitting. Use the supplied clamps to secure a leak
free installation.
Note: If your vehicle has a rigid plastic fuel
line, an alternate method to tap this line
must be used. Contact NX tech for a
trouble free solution to this problem.
2. Route the supplied red D-4 steel braided hose
from the Tee fitting to the fuel inlet side of
the box. Caution: When cutting any fuel
lines be sure to prevent any debris from
entering the fuel system. Debris can cause a
catastrophic engine failure due to clogged fuel
jets or injectors.
Wiring the System
NOTE:1 blue and 1 black wire go to positive(+12v), green wire
on the relay, and 1 blue and 1 black go to negative(ground).
Figure D
Follow the wiring diagram in Figure “D”, a wide open
throttle switch is recommended. For proper operation do
not vary from this diagram. Solder and seal all
connections with
tape or heat shrink tubing
(recommended)
Note: The Nitrous/Fuel Management System is
rated for intermittent duty only. Do not engage
Nitrous/Fuel Management System for more than 20
continuous seconds. Units that have been abused or
over heated will not be replaced under warranty.
Testing the System
1. Re-check all installation procedures to be sure
nothing has been omitted.
2. Be sure the nitrous bottle has not been opened and
the supply line is empty!
3. Reconnect the Negative battery cable.
4. Using the toggle switch “ARM” the system.
5. Test solenoid operation by using the system activation
switch. You should hear both solenoids “CLICK”. If
they do not, re-verify all wiring and retest the system.
6. Carefully open the nitrous bottle and verify that no
fittings or hoses are leaking. Correct any leaks
before proceeding.
7. Do not start the engine if nitrous has been accidentally
injected while the motor was not running! All nitrous
must be cleared from the engine before starting! A
violent intake manifold explosion could occur!
8. Start engine and check for any fuel leaks. Correct any
leaks before proceeding.
9. The PROTON Nitrous System is now ready for
normal usage.
