its 230 8v - M102

K-Jet not KE

it comes with a closed loop lambda controller only (looks like ECU)

the old loom is worn out completely (burned)

I'm confused by reference to the Bosch K injection being closed loop control. The original Bosch K was a purely mechanical injection system. The KE was the same system but with electronic control of cold start enrichment, overrun shut off and fine adjustment by an actuator on the fuel distributor unit. The original KE as fitted to my 1989 190e was open loop then when cats came in around 1990 it became closed loop but was still called KE.

Could this be why you can't find a wiring diagram for Bosch K.

I can't say this with any great authority so happy to be proved wrong but I still think that electronic assisted systems were all KE and that the diagram is not correct. Perhaps they were just using Bosch K in a generic sense without making the distinction between Bosch KE and the earlier Bosch K which was purely a mechanical injection system.
