INSTALLATION INSTRUCTIONS 3 MSD POWERSPORTS • WWW.MSDPOWERSPORTS.COM • (915) 858-3365 • FAX (915) 858-3496 Figure 2 Wiring the Launch Activation Wire. CONNECTING THE LAUNCH WIRE Most motorcycles have a clutch switch that provides a ground when the clutch is engaged. This is the default wiring of the Launch Master. If you prefer to activate the launch limit with 12 volts, disas- semble the 3-pin connector and move the Blue wire to align and connect with the White/Blue wire (Figure 2). CONFIRM INSTALLATION With the engine idling in neutral and the clutch lever released, check the LED - it should NOT be il - luminated. If the LED is On the activation wire is connected to the wrong side of the clutch switch. To verify the rpm, set the limit at a lower rpm, such as 3,000, and test the system. If the engine has trouble starting or running, check the following:

  • Ground connection
  • Coil connections
  • The two 4-pin connectors may be in the wrong position and should be swapped and tested again. Note: Due to safety controls on some applications, the launch rpm limit may be activated when the bike is in neutral or when the kickstand is down. Lift and remove the purple lock with a small tool. Lift the tab and pull on pin to remove. Insert Blue wire in slot 'C'. Reinstall purple lock. PIN SWAP FOR 12V ACTIVATION
