Question about 1997 Ford Expedition
I installed a new $400 tach (called a rally pack) on a '66 'stang. it never worked right. goes to 1500 & stops. i later realized it had a G.M. HEI ign. system. i know the old ford system works off the positive side of the coil (unlike any other systems). does any one know a solution to this mismatch?
Iam pretty sure u need a resitor a 300 ohm in between on the wire from the coil. keep in mind some dist have a tack wire some have not all
