I had
an Autometer tack on my '85 when I was racing it. I tried the diode method
and had bad luck. The tach has a switch on it to select the number of
cylinders, on my tach it just switched a different resistor into the R-C
(resistor-capacitor) network. I removed the resistor on the 4 cyl. terminal and
attached a decade resistance box and dialed in the resistance that made the tack
respond correctly. I soldered that value resistor to the switch terminals
and everything worked fine. I could pull apart the tach and get the value
of the resistor (I have a good memory.. but it is very short!) but I'm sure that
it would only work for that particular model tachometer.
