Was at the shop ready to install the trifecta tune and give before/after readings....where do they hookup the tach pickup for the cruze diesel? Tried the glow plug and nothing

Glow plugs are like heaters. They do not pulse or provide any indication of RPM. They don't even stay on the whole time the engine is running. I can't imagine any way to monitor RPM short of the crank or cam sensors. Or some sort of output sensor.

Maybe reading it off the OBD2 port or something?
