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.
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
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.
Remove 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.
