The fuel and temp gauges get power from the small voltage regulator. Its the
transistor looking thing on the back of the dash. It's plugged into a small
socket and the metal tab on it is screwed to the back of the speedo. It's right
next to the temp gauge. You probably dislodged it or maybe you broke one of
the legs on it. This regulator takes the 12v and reduces it to 10v so do not
put 12v to the gauges. The regulator may have gone bad but they don't go bad
often.

The small clock is supposed to have a harness that runs from the back of the
tach. This supplies the clock with power, and lights. If you didn't get a harness with it you can make your own pretty easily. Let me know if you need
to find out what terminal is what on the tach. The schematic is in the Bentley or Haynes books. The terminals I'm referring to are a cluster of three on the
back of the tach. As you already know the one single terminal is for the tach
signal. Rpms are much better than a large timepiece.
