The new engine is from w201, 1991, 90/122 kW/PS. But the cable comes with the original car from 1992.
Indeed the scheme didn-t help, however, thank you.
However, I made something wrong. Maybe you are right with the PSV, I tried again and the connector would fit. But then, another cable is there and has no connection.
The engine didn-t start today. Some vacuum hose are bad.
I decided to get help from a garage with better electrical knowledge... I hope they make it run again.
When I know the mistake I let you know.
