How do you install a tenzo R tachometer in a 1996 Honda civic ex v-tech?

The tach has a lot of wires coming out the back, here are what the are for:

~The RED wire goes to a power source.

~The BLACK wire goes to ground.

~The BROWN and BLUE wires are for the tach internal bulbs.

~The GREEN wire needs to go to a blue wire that is located

under your hood top right corner.

The blue wire has a black rubber cap on it.
