Where exactly do I hook up a tacometer to my 92 honda civic?

In a "Real" car (those made before computers) U hooked the black wire from tach to ground, the Red wire to +12volts on the output side of the ignition switch, the green/yellow wire to the distributor side of the coil, the white wire to your dash light circuit so the tach illumination adjusts with the rest of the dash lights. Since the hardware has changed with the advent of computers in cars I recommend U check this basic procedure with your honda dealer service dept to be sure you don't mess up your car's electronics. Good luck and happy motoring!
