QSH is the wiring connected to the iQSE QuickShifter Easy system (IQSE) and the electrical parts of the engine. Depending on the model, it can be connected to:

• Fuel injectors
• Ignition coils
• Crankshaft position sensor (CKP)

This wiring allows the quickshifter to receive the necessary signals for proper operation. The system works by detecting the movement of the gear lever and momentarily cutting the ignition and/or fuel injection for a few milliseconds, enabling gear changes without using the clutch and without closing the throttle.

Compatibility:

• QSH-Fxx = connection to the fuel injectors
• QSH-Pxx = connection to the ignition coils
• QSH-Cxx = connection to the crankshaft sensor and the main module of the quickshifter
• QSH-Sxx = connection to the spark plugs / igniters

Note: It is necessary to check that the wiring matches the motorcycle's model and year.
