Trying to help a friend 92 integra Tach not working....
 

Friend of mine has a 92 LS and the Tach isn't working, the speedometer is.

What could it be

Signal from the ECU

loose or unpluged, well plug ;)

or a bad tach

I have no more details , but thanks for your help

could be the dizz.
the blue wire on the big plug on the dizz is the single wire for the tack.
