This product has support for USB connectivity and is compatible with Windows™ XP SP3, Windows™ Vista, Windows™ 7 and Windows™ 8. It is a complete stand alone GS-911 diagnostic tool (no other GS-911 required) and is designed exclusively for the older models which have a flat three pin diagnostic connector. Applicable for Bosch Motronic versions MA2.1, MA2.2 as well as the ABS II controller.
Note: The 3-pin Interface is a stand-alone interface and does NOT require any GS-911 devices. The older and discontinued 3-pin adapter is only compatible with the GS-911usb and GS-911blu.
