300zx cluster pinout / rpm wire?

Hey guys, find below the cluster plugs, which number is the rpm wire do you know? I can't follow the wiring diagrams at all.

    Yep matches the tach wire colour from the ECU... now to find a live / illumination and ground wire! The joys of wiring in confined awkward spaces..

    Got the live and ground and rpm done .. now to try and nab that illumination wire from the back of the gauges... what a pain in the ass it is getting plugs out the back of the gauges in situ, and trying to squeeze my head between it and the windshield. Need to have it finished as soon as I go home today so I can take it for the mot re-test. Fun fun fun

    From that diagram, would I be right in saying then that pin,

     

    11 = +12v

    14 = -ve/ground?

     

    TIA.

    I'm not too sure mate, I used 9 as the illumination, and the live/earth came off the headunit (CD player). as it can be fed through into that compartment, ill see if I can take a pic of how the gauge sits :)
