It measures Revolution Per MInute (RPM). This is important in performance cars or hard working motors to keep them from overreving which can cause engine damage. On an everyday car they are used very little.

IF you have the installation instructions for the tach, it prolly tells you where to attach the tach wire. If not, call the manu. of the tach or search for their website online.

This entirely depends on the vehicle and the type of tach your referring to such as a add on tach or an OEM in dash tach. To explain how to install and OEM tach would take far to long. I would suggest a add on tach that mounts basically where ever you want to mount it. Most of these tachs explain the installation instructions. I personally recommend a tach by Autometer you can view their products on the web at the link below. , EzForJesus http://www.autometer.com/

if you mean tach/tachometer you have find an aftermarket tach driver and plug it in where the original tach plugs in

At the dist there should be one to power the dist. & one for tach signal. Unplug one & see if car starts or if tach still works. Can't really remember for sure as its been a while lol. My 1972 tach wire is brown and it has a inline fuse from the factory. Your tach wire will be connected to the negative side of your terminal witch is labeled "tach".

It should work. I have a 94 w/o a tach and put a LE version cluster with tach in. Works fine. There should still be a tach wire grouped into the harness plugs. Just unplug your old one and plug in the new one that's it.

V tach stands for ventricular tachycardia.

It should work ok if the wire for the tach under the hood is connected and I don't remember which one it is.

Since the coil is in the distributor, simply hook the tach 'trigger' wire to the out put on the side of the distributor cap marked 'tach'.

there will be a spot on back of distributor cap it will say tach run wire from there to gauge. You probably need to run a switched 12v lead as well to illuminate the tach at night. The tach slot on the distributor will take care of 'timing' the pulse to the tach. Often times the tach will have a switch setting for 4-6-8 cylinder. Read the manufacturer instructions carefully.

you can install any kind of tach you want to in your car..if you do not have a stock tach then look in your manual for the rmp sensor wire..should be blue or green coming off the distributor...just splice into it...if you have a stock tach you can just splice into the stock tach wires by taking off the dash

You don't. A tach (tachometer) measures engine RPM (Revolutions per Minute), not mileage.

A tach (short for tachometer) is an instrument that measures the rotation speed of a shaft or disk, as in a motor or other machine.

You do need a switched live to the bat terminal, but not to the tach terminal. The tach terminal is the negative side of the coil, the bat terminal is the positive side of the coil. Normally the tach terminal is for the green wire from the tach.

There should be installing instructions with the tach. If not contact the manufacturer.

hook your green wire from the tach to the white wire from the coil PAC it should be a white and a yellow wire coming from the coil. the tach should have a white wire that will be your light inside the tach a red wire for power and a black for ground.. good luck
