That's right. There shouldn't be a black wire. "S" terminal = pink (to sender in tank - left terminal on above diagram), "I" terminal = Red (12Vdc - right terminal on above diagram). The "A" (bottom/middle terminal on above diagram) terminal should be stapped over to your temp gauge as shown in the diagram that Scottymac provided above. Those are your only connections to your fuel gauge.

The black wire you are referring to may just be a chassis ground? Just check to see if you have continuity from that wire to ground.
