You don't. A tach (tachometer) measures engine RPM (Revolutions per Minute), not mileage.
Answer All cars no matter the make have to idle or they will stall. If you have a tach in your car at 70 miles and hour your tach should be around 2800 to 3200 rpm's depending on what gear you have your car in.
theirs a green wire by distributer that is for the tach
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.
yes
Yes you can
Yes you can
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
I just bought the instrument cluster out of one with the tach in it out of a junkyard. All of the wiring plugs are identical. Just a couple of screws to remove and three plugs on the back of it. 93 to 97 should be the same.
V tach stands for ventricular tachycardia.
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.
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".
