The QSX is a wiring harness/connector that must be connected to the iQSE QuickShifter Easy ( IQSE-W1 ) system.
Specifically:
- It is typically connected to the motorcycle's fuel injectors and the iQSE module.
- The QSX series includes additional electronic components within the wiring harness to prevent the FI (Fault Indicator) error from appearing on motorcycles whose ECU detects the quickshifter's intervention.
CAUTION: You must verify that the wiring is compatible with your motorcycle's model and year.
