Cluster Issues..

[JooNKing]

I have a 1990 240sx with a sr swapped in, it my first manual car and i did not do the swap myself. so the issue is that the tachometer and speedometer is not functioning but fuel and temp works.

so far i have checked the wiring to the ecu and they are correct, also its a dohc cluster.

Im a novice and dont really know where else to look. If you guys can help guide me i would appreciated it.

Thanks in advance

Remove the cluster and see harness is plugged in properly. There are 3 plugs on the back of the cluster.

Make sure the wiring is correct to the dash plug from the ECU, yellow/red for tach, yellow/green for VSS.
