Adaptor lead for older BMW models made before 2001. If your BMW has the older style 20 pin round diagnostic socket, you need this adaptor. THIS IS JUST AN ADAPTER CABLE – NOT A DIAGNOSTIC TOOL.
The socket is normally found under the bonnet – see your owners service manual.
Adaptor lead has a female OBD2 connector to 20 pin BMW plug. Allows you to convert the standard OBD2 plug on your diagnostic hardware to BMW 20 pin plug.
