Question tachometer 1994 Pathfinder manual transmission

:confused: My Tachometer does not work properly. At times it doesn't register, other times it is erratic and the needle bounces all over the scale from 0 to onto the post, other times it appears to be fine.
I think I might have a short or a bad ground but I can't find the wiring diagram to trace the wires.
I have been told the sending unit is on the cam shaft and I have also been told it is on the transmission.
What I need to know is where the sending unit is located and if it is on the transmission which connection as there are several.
The wiring diagram so I can trace it from the sender to the tach.
Where the ground is located.
