Yeah, that connector gets pretty green inside, and eventually the wires
break.  The one for your gauge is the one that connects to the single post
side of the multi switch (assuming you've got the 3 post variety).  Or, if
you look down on the connector, a have the plug oriented with the alignment
notch at the bottom, it's the upper left receptacle.  You can attach a piece
of test wire into the plug and ground it.  Turn the ignition on and check the
gauge.  You could then wiggle the connector around to see if you're loosing
the connection.
HTH,
