Junction and Wire Harness (deprecated)
Non-series components SM-EW67-A-E
This older generation Di2 wire harness comes with two e-Tube (EW-SD50) electric wires permanently attached to it and one e-Tube port meant to connect to your Junction B (SM-JC40/41) using an additional EW-SD50 electric wire.
The wire harness also includes a battery charge indicator.

You'll find this on older bikes only. It does not have a charge port, so it can only be used with an external battery.
The lack of a charge port also means you cannot use the SM-BCR2 charger/pc interface to update firmware. You would need the newer junctions SM-EW90 / EW-RS910 or one of the displays for that.
This junction is not compatible with the BT-DN110 internal battery or the BM-DN100 ext. battery mount.
