Was anyone actually able to get a tach amplifier and gauge from a 300D and plug it in to an existing rpm sensor in their 240D? It seems there were several discussions, but no specific success stories.

Tach seekers- Thats the thing- the sensor on my 240 (looks exactly like the one on the 300 I owned for 3 months, not sure about the connector) and is mounted properly, same place and everything, but sends an RPM signal to the EGR computer (at certain rpms and engine temperatures the 240D's of this vintage (1982 and 83) have a computer that tells the egr valve when to open..., the black box is in the passenger side footwell IIRC.
The 300D tach signal goes from the pulley, through the sensor, to a wire to the tach amp (the cigarette fix thing), then from the tach amp to the tachometer.
If the sensors are the same part number (which I cant find out, not sure how to save going and looking for a p/n on both, and they are tough to see/get at in the first place on an OM617) then the amp and tachometer should bolt/power right up. Thats why I'm asking if someone can look up those part numbers for me.
This could be another 240D easter egg (appl to '82 and '83 models only =)
