so your not even close on that.

if your signal is bad out of the ecu use pin 22 iirc for cas signal, just tap into it and shoot it to the back of your cluster where the right colored one is.

makes sure your coilpack harness is grounded to the back of your head and firewall also, and all ignition wiring is intact.

now gtfo

Exactly.

Check that wire from the cluster, through the dash, to the ecu.

If your getting the correct signal and the tach still is not working. Your cluster board is shot. So get a new one.
