As the title says, my tach is not working. I recently just fixed my speedometer to get it to move and work, but I still don't have a tach. I've been looking thru wiring diagrams and the fsm, but I'm still unsure of where to start looking for an issue. My car is rough so I wouldn't put it past a stupid broken wire or something somewhere. Where does the tach get it signal from? I know there's a pin for it on the ecu if I'm not mistaken. Just need some direction so any input would help.

Every Nissan tachometer that I've worked on that wasn't working has always ended up being a bad tachometer. I've never run into a wiring issue that caused it. Only thing you can do is get a multimeter and check the circuits, following the wiring diagrams in the FSM, to make sure they are not open nor shorted.
