What is the Shimano TL-EW02 Di2 plug tool for?

The TL-EW02 is Shimano's E-Tube Di2 wiring plug tool, used for inserting and removing Di2 E-Tube wire connectors from junction boxes, derailleurs, and other Di2 components. Di2 connectors are small and seated firmly to prevent accidental disconnection during riding -- the TL-EW02 provides the correct leverage and contact point to extract them cleanly without damaging the connector or the component socket. An essential tool for anyone setting up, servicing, or reconfiguring a Di2 system.

Compatible with Shimano Di2 E-Tube wire connectors across all Di2 generations using E-Tube wiring. A must-have for Di2 installation and service work.
