uhm, you just put a 1996 KA into a 1989?

I’m pretty sure you need a DOHC tach for a DOHC motor.

SR/KADE can use the same tachs

CA/KAE can use the same tachs.

Correct me if I’m wrong anyone…

what wire harness/ECU did you use, Itake/exhuast mani’s? Did you modify the dash or engine harness mating plugs?

step 1, take cluster out, step 2 remove tach by 2 screws holding it in, step 3 swap dohc tach in.

Step4 make sure the white plug above the ecu has been wired up to match wires.

done.

or near enough.
