    Hi people, anyone know where the OBD socket is on this machine. PS, its not under the passengers seat and its not next to the fusebox.

    Z31 is pre-OBD so no socket. The ECU does have an inbuilt diagnostic function however with flashing LEDs viewed through a port in the side...

    Thanks for that. I'll give it to my diagnostics man. I have also downloaded a full workshop manual (US Spec, but same info for ECU diagnostics)
