Применяемость детали указана верно. Про Е-23 знаю. Так ведь тоже хрен найдёшь именно такую! Период выпуска - 2 года. Маловато...
вот 25 pin
My notes after looking through 91 M30 ETM. Just trying to compare some things and see if I can decode the 25 pin X20 connector,
B6230 oil level sender
T6150 ignition coil
B6231 oil pressure switch
B6233 - afm
Y6130 - icv
S6250 - throttle switch with no egs
S6251 - throttle swithc with egs

Fuel injector wiring 1,3,5 is BR/WS
2,4,6 is BR/GE
Switched by the ECU, common ground.
Cylinder 1 is at the front of the car.

That's all I got so far, it's a little hard to follow ETM as it's split into 100s of pages.....
Interesting that the same connections in 89 535 ETM are different...
