    It Prevents corrosion of the glass to metal seals in contact with the cooling water by acting as a sacrificial anode. Reconnect it immediately.

    The wiring should be near by, look under the frame.

    do you know which pin it should be hooked to?

    can it be that it should be at ground potential?

    Laserman532 worked at the factory, he'll chime in here in a minute. I cant remember, off the top of my head, because I have sold every 164/165/168 I've ever gotten my hands on.
    There is a wire in contact with the water under the red boot.

    sams laser faq says

    Oh and yes, a sizable current is leaked through the tube assembly to the water, preferably from a designed-in ground wire that is installed at the cooling water input on the tube at the cathode end (thin red wire). Otherwise it comes from the anode block, which it will probably rapidly corrode.

    so does this mean that i should connect it to the anode?

    im starting to talk to my self through PL

    The wire should be connected to the anode. There should be a thin red wire coming from the anode to somewhere near the cathode. As MG said, it's underneath the frame.

    Do make sure the red boot covers the pin completely. The wire (and anything conductive connected to it) is at anode potential.
