You will have to find the coil first.
The Avenger did not exist as a 1994 model.
Buy an instrument panel with a tach from a junkyard. The wiring is in place and is plug and play.
in side dist under pickup coil
Why?
A cog and gear attached to the transmission which turns a worm driver attached to the tach
Bad white wire
if you mean tach/tachometer you have find an aftermarket tach driver and plug it in where the original tach plugs in
sounds like a dead short in the tach wire, trace the tach wire and see if it the wire insulation has been broken.
check all of your fuses all you have to do is do an ohm test probe one side and the other side you dont even have to take them out
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
it's located at the bottom of the distributor
from the engine computer, which gets its rpm info from the crank position sensor
