The QSX is a wiring/connection adapter (harness) that connects to the iQSE QuickShifter Easy (IQSE-W1) system. Specifically:

• It connects to the motorcycle's fuel injectors and the iQSE module.
• It includes additional electronics within the wiring to prevent the occurrence of FI (Fault Indicator) errors.
• It is compatible with motorcycles whose ECU detects the quickshifter intervention.

A check must be made to ensure that the wiring corresponds to the model and year of the motorcycle.
