I'm trying to read the wiring diagram in the Haynes manual (it's in color, so that helps) and here's what I can see: the water temp sensor, tach, and tach light all go into what appears to be a five-pin connector(R/BL, BR, BK/Y, BK, and Y wires); the Black/Yellow lead serves as the ground connector for your headlamp, but also your front left turn signal - so that doesn't make sense. However, the BR wire from that lead serves as the power wire for your horns, so that helps. The BK/Y of the fuel gauge also grounds to the same lead (the sensor is a two-prong connection under the saddle - the gauge itself operates on its own circuit). I'm pretty sure that connector can be found under your left front engine cover (two screws - big phillips head) - see if they forgot to hook that up, or didn't fully hook it up. I'll go out and see what color that connector is - back in a flash.
Hmm...short term memory here on wire colors, but I think the connector is probably the red one. There's also a five-pin brown connector located in the same vicinity - might as well check both while you're in there.
