S14 SR Swaped Tachometer not working

[E7-S14]

After my swap my tach didn't worki bought the car as a shell(no motor) and dropped the sr ini amused the tach worked..

well the guys that wired my swap said that the problem was in the tachometer itselfso i bought another gauge cluster with a working tachand it still doesn't work.

What else could it be causing my tach not to work?

everything should work since its a 96 S14 SR in a 95 s14 chassis

If i were to buy an aftermarket tachometer what rpm signal should i use to ensure it will work?

[E7-S14]

any help here?

Sounds like the wire isn't connected in the dash harness next to the ecu.

that's what im guessing.ill have to bring it back to the guys that wired it.

eh..

about the aftermarket tach.if i go that route(which i probably will)what rpm signal will work no matter what.is there more than one rpm signal?
