hey guys .... I have a jb4 in my bmw f30 335i with n55 motor from 2012 with pwg and would like to install the box in my bmw f10 535i n55 with pwg.
At my f10 is wiring harness type a and in my f30 is wiring harness type b.

Meanwhile I found out that the sensors are actually exactly the same, only the design of the plug has been changed. actually, only the plug of the plug was changed. the plugs were made by the company hirschmann, and these probably had problems, the shutter did not last properly and not long and water came into the plug. Therefore, a new connector (Type B wiring harness) was installed. Now I would like to build an adapter, with which I build the jb4 box with the wiring harness type b harness to my f10 n55 wiring harness a block.

That's why the plugs are needed individually, and these are very hard to find. at bmw I find only a part. at alibaba I found all, but sell only from 1000 pieces :-(

These plugs are also interesting for anyone who wants to install the 3.5 bar sensor, because the adapter of BMW costs around 140Euro with us and is nothing more than two plugs and four cables.

Maybe someone else knows a way where I can buy plug individually.

here the already found part numbers:

Brand: HIRSCHMANN

Harness plug typ b

Here are the original part numbers of Hirschmann
male 805-122-541 (4 way connector)
female 872-617-541 (4 way connector)

bmw part number
male 12527549033
female 18302411427

Harness plug typ a

Here are the original part numbers of Hirschmann
male 872-440-501 (4 way connector)
femal 872-536-501 (4 way connector)

bmw part number
male 12527513331
female ?????


who can help me with the search on the plug?




Many, many thanks in advance.

best regards from germany
