- How to: Electric Tachometer rig with LED's?
Basically, what I am wondering/like to do is to
somehow, rig up
more LED's to a stock (ford) electric tachometer.
From what I understand, an electric tach works like a
based off of the amount of current to the tach, the
rpm's of the engine.
How would I say 1. hook an LED up to come on at a
specific RPM and
2. hook up several LED's to display 5,000-5,500, then
5,500 and up
different color?? basically like a drag strip start
