Do you guys know where and what wire I can tap into for the tach signal? I know installing an aftermarket tach can be tricky sometimes with DIS ignitions.Installing an Autometer tach in place of my stock unit if possible..Thanks..

On a1990 it is E1 on the C-100 connector located just to the left of your left toe as you drive the Z; look for the white wire.

Edit: might want to verify with your FSM to be sure it is the same on later model Zs.
