Installation of the NCC-002 Nitrous Control Center 18
3.1.2 One Stage of Progressive Nitrous and Fuel
Use this configuration to control the one stage of progressive nitrous and fuel.
•
Connect the solid red wire labeled "12 VOLT PWR" to the "+12 Volt" terminal on the NCC-002 and to a fused
and switched 12 volt DC source.
•
Connect the solid black wires labeled "GROUND1" and "GROUND2 to the "Ground1" and "Ground2"
terminals on the NCC-002 and to the battery ground stud.
•
Connect the yellow wire labeled "ARMING INPUT" to the "Arming Input" terminal on the NCC-002, through a
WOT switch (alternatively, the TPS can be connected to the TPS Input), and to one of the wiring terminals on
the Nitrous Arming Switch. The Nitrous Arming Switch output should then be connected to the input of the
nitrous solenoid(s). If the combined current load of the nitrous and/or fuel solenoids exceeds the capacity of
the NCC-002, LPE recommends controlling the solenoids via relays. Depending on the current rating and
quantity of the solenoids you are using, it may be necessary to use separate relays for each of the nitrous
stages. If using relays to control the solenoids, see example wiring instructions in
section 3.1.3.
•
Connect the striped dark brown wire labeled "N2O SLND 1" to the "N2O Solenoid1" terminal on the NCC-002
and to Nitrous Solenoid 1.
•
Connect the striped tan wire labeled "FUEL SLND 1" to the "Fuel Solenoid1" terminal on the NCC-002 and to
Fuel Solenoid 1.
•
If the user desires to activate the nitrous using engine speed, to data log the RPM, or to control a shift light,
connect the striped white wire labeled "TACH INPUT" to the "Tach Input" terminal on the NCC-002 and to a
suitable RPM Signal Source. The RPM signal source could be the tachometer output lead of the vehicle, the
switched side of the ignition coil (negative side), or the 5 volt RPM reference signal. See
Appendix C: Tables
and Diagrams for the location of the tachometer output wiring on some common GM vehicles.
•
If the addition of a shift indicator light is desired, connect the solid green wire labeled "SHIFT LIGHT" to the
"Shift Light, +12V" terminal on the NCC-002 and to the shift indicator light.
WARNING: The fuses that are positioned in series between the 12 volt power source and the relays are
labeled as 30 amps each. It is important to note that the amperage rating for these fuses are just
suggestions and that the amount of current that your solenoids can pull will determine the correct fuses
for your system.
