This is a genuine BMW repair cable ABS, part number 61 12 8 376 019. The number stamped on the part is 61128376019; BMW's catalog files it under the short number 8376019. You will find it on our Electrical shelf, under Auxiliary cable. It supersedes the older number 8365684, so a part carrying that number is the same part.
It fits every E36 body style (318i, 318ti, 320i, 323i and 325i, 1992–1999), with the M40, M42, M43, M44, M50 or M52 engines — and the European-market versions.
BMW draws it on 2 diagrams, among them Wiring set (61_0060) and Various Additional Wiring Sets (61_0931). It weighs about 234 g (0.5 lb).
