3. Refer to Figure 2 for basic hookup. Figure 3 shows
hookup for a system with independent control of
nitrous and fuel flow (refer to page 16 for details).
All signal and low current connections (thin lines)
can be made with 18-20 AWG wire. High current
connections (thick lines) require 14 AWG wire.
4. Working with clamping terminal blocks. All
connections to the controller terminal blocks must
be clearly identified either by means of distinct wire
colors or the use of wire labels. If you use distinct
wires colors, mark up Figure 2 or 3 for future
reference. Refer to the Appendix for recommended
wire labels. Wire should be stripped back 3/16-1/4
inch. No bare wire should be visible outside the
terminal block. Use a miniature Phillips or flat
screwdriver to tighten the screws.
5. Solenoid connections. Relays with a minimum 40
amp rating are required. If your nitrous system
uses large solenoid valves, you should use the
heavy duty P&B/Tyco VF7 series 70 amp relays
listed in the Appendix. The use of 50 amp fuse
blocks such as the Littlefuse Maxi Fuse series
listed in the Appendix is recommended. Power
connections from the fuse blocks must go direct to
the battery positive terminal. The ground
connection from the solenoids must go to a chassis
ground stud or may be connected direct to the
battery negative terminal. Use 14 AWG wire. Keep
power and ground connections as short as
possible.
6. Arming switch and status LED. The hookup
diagrams show terminal numbers for the
recommended C&K DM series illuminated power
rocker switch (refer to the Appendix for details).
You can also use a separate switch and LED. The
controller has an internal 1K ohm current limiting
resistor on the status LED output and can directly
drive any LED. The status LED output cannot drive
a conventional lamp. Most vehicles will have an
accessory fuse that can be used as a source for
the switched and fused +12V power connection.
Refer to the Appendix for recommended fuse taps.
7. Manual purge switch. If you require manual purge
capability, connect a momentary switch as shown.
Refer to the Appendix for the recommended C&K
DM series rocker switch.
8. Throttle position sensor (TPS) signal. Most
vehicles manufactured since 1981 will have a TPS
with 0-5V output located on the throttle body or
carburetor. Refer to the vehicle wiring diagram for
details. You can check the TPS signal with a DVM.
Some late model vehicles with drive-by-wire
electronic throttle bodies will have a dual output
accelerator pedal sensor. The signal voltage on
one output will rise with increasing pedal position
and the other output will drop. Connect the nitrous
controller TPS input to the rising signal. Solder this
signal connection and wrap with self vulcanizing
electrical tape (refer to the Appendix). If a suitable
0-5V signal is not available, you can use a wide
open throttle switch as shown in Figures 2 or 3.
9. RPM signal. This connection is required to utilize
the full capabilities of the controller. Depending on
your vehicle type and engine control, there are
three possible sources for the RPM signal:
a. High level signal on the Coil- terminal of
most inductive discharge type
ignitions. This includes most original
equipment (OE) ignitions except coil-on-
plug with integrated drive electronics. For
distributorless systems with multiple coils
or coil packs, you can use any one of the
Coil- signals. Refer to the vehicle wiring
diagram for details. The Coil- terminal will
connect to an ignition module or engine
control module (ECM). The Coil+ terminal
will connect to switched +12V.
b. Tach signal (preferred for best noise
immunity). The controller is compatible
with industry standard 12V square wave
tach signals such as what would be used
to drive an Autometer or similar
aftermarket tach. Most aftermarket
capacitive discharge (CD) ignitions
including the MSD-6 and Crane HI-6 series
have a tach output that you can use.
c. Low level logic signal. This type of signal
is found on late model vehicles, including
many imports, that use coil-on-plug with
integrated drive electronics. Refer to the
vehicle wiring diagram for details. You can
use the signal that goes from the ECM to
any one of the coil-on-plug units.
Unless you are using the tach terminal on an
aftermarket ignition or a screw terminal on a coil,
you should solder the RPM signal connection and
wrap with self vulcanizing electrical tape (refer to
the Appendix). During initial setup, you must
configure an RPM signal level jumper inside the
nitrous controller. Refer to the Initial Setup section
on page 15 for details.
