ADJUSTABLE CONTROL MODULE for Edelbrock Harley-Davidson Nitrous Systems Kit #72230 INSTALLATION INSTRUCTIONS Please study these instructions carefully before installing your new Edelbrock Nitrous System. Failure to follow instructions will void warranty and may cause damage to parts and/or personal injury. If you have any questions or problems, please call our Technical Hotline at: 1-800-416-8628, 7:00 am - 5:00 pm, Pacific Standard Time, Monday through Friday or e-mail us at edelbrock@edelbrock.com. 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. 2. Make sure that the Nitrous Module Housing is easily accessible. Remove any components from the motorcycle that could be blocking access to the unit. 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 Chrome Cover Plate, to prevent damage when the cover is removed completely (Fig. 2). This will allow you access to the Control Module for the proper removal and installation of your new component. Fig 1 3 4. 5. Remove the wire clamp located on the inside of the backing plate (Fig. 3). 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) 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. 2004 Edelbrock Corporation Brochure #63-0131 Page 1 of 4 Fig 2 Fig 3 Fig 4 Catalog #72230 Rev. 5/04 INSTALLATION 1. 2. 3. 4. 5. 6. 7. 7. 8. 9. 10. 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). 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). 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 Fig 5 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). 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). 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” Fig 6 terminal to the fuel solenoid wire terminal and the “NOS” terminal to the nitrous solenoid wire terminal. Route the red and green wires through the wire port of the backing plate. Connect the green wire, labeled “TACH”, to the tach lead. Leave the red wire disconnected at this time. 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. 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. Install the Chrome Cover Plate using the four bolts and washers that you removed previously. Connect the red wire, labeled “13.8V”, to the battery or Fig 7 key activated circuit breaker. 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. 2004 Edelbrock Corporation Brochure #63-0131 Page 2 of 4 Catalog #72230 Rev. 5/04 WIRING DIAGRAM Wire Color System Origin Destination Red Battery Voltage Nitrous Module Harness Battery or Key activated circuit breaker Black Module Ground Nitrous Module Harness Ground to cylinder head bolt Green Tach Trigger wire Nitrous Module Harness Factory Tachometer lead or Coil Orange Yellow System Arming Wire Horn interface wire Top Terminal of Arming Switch Center Terminal of Arming Switch Blue Horn interface wire Gray SF/DF Single or dual fire Ignition lead Nitrous Module Harness Horn power lead.

DF* Ground wire to Module plate Catalog #72230 Rev. 5/04 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 between 2000 RPM and 5000 RPM and shut down between 5250 RPM and 7125 RPM. You should consult with the engine 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! Examples: Shown above: The left pot is at setting 2 2=2400RPM activation The right pot is at setting 8 8=6250RPM de-activation Shown above: The left pot is at setting 7 7=3400RPM activation The right pot is at setting A A=6500RPM de-activation Edelbrock General Warranty It is the constant endeavor of Edelbrock Corporation to give our customers the highest quality products obtainable.
