Hello everyone. Happy to be part of the World's biggest Mercedes-Benz society.
I'm trying to retrofit my E-class with cruise control. So far I only have e donor. W124 with 2000cc engine manual gearbox. I have M111.960 engine with manual GB. From what I know I need the curator, the cruise clutch, a simple button under the clutch pedal and the module. Wiring as well. I'll be very happy if you guys can give me more info. about this adventure I'm in. Do I need something else? Did I miss something? :nerd
Cheers.

Hard question....

The main reason why your posting has not yielded any results is because benzworld mainly deals with US spec cars, and all those cars got at least 6 cylinders and cruise was a standard feature.

No 4 cylinders were ever sold.

I highly suggest you hit up a European based MB forum for your specific question. See link

However, I can tell you on the M111 you need at least a throttle body that supports the cruise function, along with the electronics, wiring looms, stalk, brake and clutch switches, etc, etc, etc.

It is not as easy as on the older mechanically injected gasoline engines like the M102 (predecessor to the M111) and the diesel W124 cars that used a cruise control amplifier.
