Thread: RPM gauge question

hey guys im new here. i recently just traded my 240sx for a 200sx ser with an sr20de motor in it. my rpm gauge doesnt work but everything else on the cluster works.. if anyone knows this problem please help me out cause im new to these cars. thanks.

Are you using the sr20de ecu? Find the DE ECU pinout diagram, and then run the wire from pin no 2 to the screw behind the tacho.
