The diesel needs a groove cut in the pulley. The groove causes a disruption in the magnetic field which the pickup senses.
I mounted a (300d) tach in my 6.2 diesel Blazer (<- comes with a bracket for connecting a magnetic probe for timing & rpm). I fab'ed a bracket to mount the MB pickup. Worked like a charm, , , , ,

it's a pin on the harmonic balancer that spins.
below is a picture of the pin when the pickup sensor wire is removed, a side shot
as well as another clear shot of the pin when i was taking the old pickup sensor off and then the new sensor on
and within that picture i put an arrow, to ask if i loosen this bolt can i shift the bracket to make it a bit closer ?
this car was a m110 engine, but now has om617. I bought a diesel tach+ tach amp + pickup wire seperately
