Tachometer not working

[1968rick]

My 68 Satelite has a factory tach. The engine has Mopar electronic ignition. was this stock or an add on?
How to get the tach to work with the electronic ignition?

I don't remember, electronic didn't come out until 72? or so, certainly not 68. It should be hooked to the coil NEG terminal. I don't know any reason why it would not work if the tach is good and wired up correctly Should be a blue to power and a green through a grommet on the firewall to the coil NEG

Tach should work but it will not be accurate, maybe +/- 500 rpm with some needle bounce depending on what ecu you are using. After I started shifting at 6000 I wired up a bosch gauge on the side of the steering column to get an accurate reading. 68 had points ignition.
