Tach hook up

[stang9150]

I have a 79 ford fairmont station wagon with a 200 inline 6,it has the duraspark ignition any idea where to tap in for a tach signal.I was thinking the coil but there are 2 wires not sure which one to tap.I know its not a stang but it is a fox and will have a 302 5 speed soon

Negative side of the coil is the tach pickup on the mustangs, not sure on your 79 Fairmont. Although if it has a duraspark...
