Is it a V8 M60 or a straight 6 M30B30 (R6 in German) engine?
For the R6 I find 20 pins only under main group 12, subgroup 31.

But also the V8 has only 20 pins as far as I can see.

Anyway, if you find on the spare parts catalog the number and the name in English, copy and paste the number into here and then you have the German name and the German price

And this is the wiring harness for DME for V8

Just checked once more in the Bentley repair Manual. What you means is the main engine harness connector, which has 25 pins. On a 730 R6 it is near left front strut tower, on a V8 740 it is on the right cylinder head, beneath top engine cover. And on a 750 connectors are near left front strut tower.

Blue/yellow wire # 1 is for dynamic switch and blue/white wire # 2 is for static switch. for oil level sensor.
The others??

@Reinhard & all: hast Du die Farben und Bezeichnungen fuer der Stecker NEBEN der Diagnosebox fuer das Motormanagement, also Pin 1-25?

its very hard for me te explain becouse its a friends car i havent looked at it and he lives far away from me but he cant use a computer

the car is a 730i with a straight 6 motor think its the one u call r6 M30B30
and the connector is placed near left front strut tower close to the fusebox
and he say to me that it has 25pin but not all of them are in use so maybe its only 20 pin
think ur right when u say main harness connector

i found som pics of the socket and the name of it was x20 sw or x21 sw
and some number i dont understand B260007.00

im not interested in the diagnostic but it looks the same

he is going to look for the colours tomorrow i hope and see if they matches with that u say

hope this help u som more and im very greatfull fore all the help u give me so far
vielen dank /martin

I think what you mean is besides the diagnostic socket lin on the right.
= engine harness connector. It is not mentioned here by name, but you can see it. Between the diagnostic socket and the fuse box the black round covered connection box. And there are 25 pins inside.
