The information on the GS Fiche re the various sockets in the wiring harness is incomplete and is a generic list of repair sockets for all models. Dealers are expected to splice new sockets onto the harness rather than obtain new sockets and pins. Many plugs and sockets are common to the cars and the socket bodies are available separately if the part numbers can be found.
There are 2 numbers on many sockets, A manufacturer number and a 7 digit BMW number. RealOEM can identify the part from the BMW 7 digit No. Car service departments can often identify the pins needed from the socket body number. Socket body costs can be as low as $US2 and pins under $1.
The information here is the start of identifying the sockets and adding the pin information. It is far from complete.
The sockets are common to all the F and G Series models unless otherwise specified.
