Hi, all! Happy 2019!
Dunno whether the question is in the right forum or not: Does anyone out there know of a retro-fitted cruise control for a manual W123 converted from an auto? I still have the vacuum-operated CC 'switch' on the steering column, but would prefer something electronic. Arduino, perhaps?
Cheers

I don't know what engine you are running, likely OM617, but on the EDC engines (OM605/OM606) I have cruise control built in to my DSL1 ECU, all that is needed to make it work is a couple of resistors and a pair of switches.

The Rostra 250-1223 is all you'll ever need. I actually installed one on my old W123 280E and used the stock cruise stalk. A bit pricey, but really worth having a look at.

Thanks, Guys. Mine is a 617 engine. I've looked at the Rostra website, no info on Benzes, but I'll keep looking.

The Rostra is universal - just hook the actuator cable to the throttle linkage and the electrical connections. You can use the Mercedes-Benz cruise stalk with a few modifications - there's a specific forum thread elsewhere (just Google it).

I was going to install one of these in my car because I was doing 8.5hr road trips for the last few months but have moved back home so probably won't bother any more.
I was wondering if the speed sensor could work off the crank, that way the engine might be useful for driving something when in neutral
