Genuine BMW part 61 12 2 153 330: Auxiliary connecting cable. The number stamped on the part is 61122153330; BMW's catalog files it under the short number 2153330. You will find it on our Electrical shelf, under Auxiliary cable. It supersedes the older number 0427842, so a part carrying that number is the same part. BMW has since replaced it with 2336509.
It fits every E46 body style (320i, 323i and 325i, 1999–2006), with the M52, M54 or M56 engines — and the European-market versions.
BMW draws it on 2 diagrams, among them Auxiliary connecting cable (65_1786) and Auxiliary connecting cable (65_1789). It weighs about 10 g (under 0.1 lb).
We have not had one on the shelf yet. Request it and we will tell you when one comes off a car.
