NOTE: Before starting this project, be sure that the motorcycle is cool enough to work on and that the battery is
disconnected (negative cable first). Failure to disconnect the battery could result in electrical damage to the adjustable
control module and/or personal injury. PRE-INSTALLATION
1. Make sure that the Nitrous Module Housing is easily accessible. Remove any components from the motorcycle
that could be blocking access to the unit.
2. Remove the Chrome Cover Plate from the Nitrous Module Housing unit by removing the four allen head bolts from
the top of the cover plate (Fig. 1). Be sure to disconnect the wires routing to your arming switch, mounted on the
ChromeCoverPlate,toprevent damagewhenthe coverisremoved completely(Fig. 2). Thiswillallowyouaccess
to the Control Module for the proper removal and installation of your new component.
ADJUSTABLE CONTROL MODULE
for Edelbrock Harley-Davidson Nitrous Systems
Kit #72230
INSTALLATION INSTRUCTIONS
3Remove the wire clamp located on the inside of the backing plate (Fig. 3).
4. Disconnect all of the Nitrous Control Module wires from their destinations.
This entails disconnecting all of the following connections:
• Battery (red wire)
• Module ground (black wire)
• Tachometer lead (green wire)
• Single Fire or Dual Fire Mode Wire (gray wire)
• Arming switch (orange wire)
• Fuel pump power (blue wire)
• Fuel pump ground (black wire)
• Solenoid connectors (black plastic clips)
5. After all connections have been removed, remove the Nitrous Control Module
from the backing plate. This can be done by using a flat head screwdriver
to pry the module off the plate (Fig. 4). The module is held on by double
sided tape. Scrape off any remaining tape from the backing plate to ensure
that your new Adjustable Control Module mounts securely.

INSTALLATION
1. Install your new Adjustable Control Module onto the
backing plate in the same location as the Control Module
that you just removed. Install the module so that the
adjustment controls are located on the bottom of the
module (Fig. 5).
2. Connect the black ground wire off of the adjustable
module, labeled “GND” to the backing plate using the bolt
that you previously removed (Fig. 5).
3. If using a Single Fire Ignition, leave the gray wire labeled
“SF/DF” loose and tape or cut and apply a butt connector
to the end of the wire so that it cannot contact anything. If
using a Dual Fire Ignition, connect the gray wire labeled
“SF/DF” to the same bolt as the black ground wire off the
adjustable module (Fig. 5).
4. Route the blue and black fuel pump wires, labeled “PUMP”, through
the wire port on the backing plate. Connect the blue fuel pump wire
to the positive (+) terminal of the nitrous system fuel pump and the
black fuel pump wire to the negative (-) terminal of the nitrous
system fuel pump (Fig. 6).
5. Connect the two black male solenoid clip terminals to their
corresponding female clip terminals routed through the wire port of
the backing plate (Fig. 5). Be sure that you connect the “FUEL”
terminal to the fuel solenoid wire terminal and the “NOS” terminal to
the nitrous solenoid wire terminal.
6. Routethered and green wires through the wire port of the backing plate. Connectthegreenwire, labeled “TACH”,
to the tach lead. Leave the red wire disconnected at this time.
7. Using the wire clamp that you previously removed
during the Nitrous Control Module removal, route all of
the excess wire that is now in the housing through the
loop and mount this clamp in its original location, such
as depicted in Fig. 3.
7. Connect the orange wire, labeled “ARM”, to the top
terminal of the Arming Switch. Connect the remaining
wires that you previously disconnected from the
arming switch to their appropriate terminals on the
switch.
8. Install the Chrome Cover Plate using the four bolts and
washers that you removed previously.
9. Connect the red wire, labeled “13.8V”, to the battery or
key activated circuit breaker.
10. Your Adjustable Control Module has been supplied with an adjustment settings sticker for your convenience. This
sticker can be mounted wherever you feel is convenient, but we recommend placing the sticker on the inside of
the Chrome Cover Plate as depicted in Fig. 7. This will keep the sticker from being misplaced, as well as be
located in a convenient location for reference when you are adjusting your settings.

ADJUSTING THE CONTROL MODULE
The settings diagram located below is the same as the sticker that you previously installed. This diagram contains crucial
information that will allow you to select the setting that you would like your nitrous system to activate at as well as shut
down at. Depending on your engines configuration and power, the nitrous system can be programmed to activate at
between2000RPMand 5000RPM andshut downbetween 5250RPM and7125 RPM. Youshould consultwith theengine
builder and/or manufacturer to find out the rev limit for your specific engine. NEVER exceed the RPM limit of your
engine. Severe engine damage may occur!
Adjusting your control module is done very easily using a small flathead screwdriver. First, select the RPM that you would
like the nitrous system to activate at using the chart below (or the sticker supplied with the kit). Set the arrow on the left
pot to the correct number or letter for the setting you would like. Last, select the RPM
that you would like the nitrous system to de-activate and set the right pot to the correct
number or letter for the setting you would like. Below are two examples of different
settings. Once these setting have been made, your system is ready to run!
