ln130 rev counter

[Reece2.4]

Which wire behind the instrument cluster is the Rev counter signal wire? I know the 1uzfe uses the Rev signal from the ignitor so just run a wire from the ignitor to the tacho wire but which wire is the tacho wire, there's like 4 plugs behind the speedo

Not sure which one it is behind the panel but from memory its run from the injector pump which has three wires on it I think, earth, live and rev counter.
You could try and trace it back to the panel or use a continuity meter to find it.
