What color is the "other" wire? I'm guessing brown. If so,
pink goes from fuse box to terminal closest to driver's door--
Empty side; and
brown from term. closest to pass. door, or
Full side, to tank sender. **Please note: there just may be 2 brown wires in the dash area which should not be confused:
one goes to fuel tank; the
other goes to license plate light.**

The gauge-to-sender-wire can cause 2 problems. If it is "open", the needle stays on E all the time; if it is shorted along its route to sender at tank, it reads F all the time. Temporarily running a dedicated wire from gauge to sender(like straight from gauge, across back of seat, and to the sender) will eliminate
EITHER problem. You then know what to do!
If problem persists after you have verified voltage to the + terminal, and run a dedicated wire, as described, to sender, then gauge is, as you apparently are already convinced, defective. In working on possibly 12-15 of these sixties-gauges over a number of years (from earliest in ~1975, to latest in ~2011), I've
NEVER run across a bad gauge--just bad wiring, defective senders, and 'sinking' floats. In all these repairs, iirc I actually never bought a sender
OR a float; all I recall were repairable, mainly curable via wire-repair or soldering. BUT I DON'T RECALL WORKING BEHIND AN EARLIER TRIAL-AND-ERROR EXPERIMENTER WHO COULD HAVE RUINED A GOOD GAUGE. Please do not think I am downgrading experimenters, as we all likely have learned untold info by doing so; but on electrical repairs, we can easily "smoke-test" a suspect component.

Hang in there, keep us informed, and you 'and this forum'
WILL get the problem turned into history!
