Answer 1

Check with the manufacturer and get a wiring schmetic or at least the installation instructions. You will need one wire to the 12V supply, one to the ignition, a ground wire, and a wire to the dash lighting circuit, so you can see the tach at night.

Buy a new gauge with instructions. The red wire probably goes to +12 volts and the black wire to ground, that's all I can say. Or you could try the web site of the company that made the gauge.
