Modify an m104 tachometer to work with an om603?
Modify an m104 tachometer to work with an om603?
I appreciate any experience or ideals with the problem.
EDIT: Looks like one guy was able to do it on a 190d but I can't find any details.

The tachometer on my 87 300d died and I wasn't able to fix it. I have a spare 94 e320 cluster which I was planning to use parts from for the improved lighting. For shits and giggles I plugged the e320 tach into my 300d and it pegged at 7k as the engine was idling. The 300d reads rpm off the starter gear and the e320 reads off the 3 timing windows built into the flywheel. Has anyone successfully modified a gas tach to work in a diesel? The car already has an M103/M104 flywheel from the 5spd swap so I guess one option would be to move the crank sensor or add a second crank sensor so it can read the 3 timing Windows.
I appreciate any experience or ideals with the problem.
