Hey guys,

according to the diagram, #3 pinout is for the TACH, but on my 180sx ecu harness, the wire is missing...

What can i do? Am i missing something?



Thanks,

Sonny

Sonny,

A late model 180sx Type X will have a different ECU pinout.If Pin 3 is missing, its likely that Pin 2 is yellow/red, which is the tach.

Make sure your ECU is a J4 ECu and NOT 62/E5...If you have a standard S13 ECU, then you will have to repin the ECU plug.

Good luck.
