A Note From "Instrumentsrus"
In the last several months I've had many requests to convert pre-1974 Ford tachometers to GM HEI.  In 29 years of authorized Ford service I could not figure this out; since I consider Ford's in-line tach hookup to be the most reliable and accurate system. However, through many intelligent clients I've talked to, I found out that Pertronix is now offering their reliable electronic conversion kits for 1974 up Fords. In 1974 FoMoCo changed how they derive their tach signal from the coil. Ford switched to the same style as G.M. and Mopar. I found out many 1973 back clients did not understand what they were installing or purchasing.  If you own a pre-1974 Ford tachometer, make sure you know what you are ordering.  The 1964-73 Ford in line tachs will not work with the HEI distributor Pertronix is offering. They need to be converted and Instrumentsrus can do this, but it is not necessary! It is never a good idea to convert an in line tach to the minus side of the coil!  All 1964-73 Ford Tachs need the following system!!!!!
Pertronix Ignitor Electronic Ignition
Part# 1281
I hope this will assist you in converting your conventional points system to a reliable Pertronix electronic system!!!
Note: Pertronix has introduced the Ignitor2 coil which has ballast resistance in the coil!

NOTE:
If you are using MSD call there tech support at 915-855-7123 before calling us!  Due to the complicated set up MSD uses on Ford tachs, we are not able to answer all the questions concerning their system. For 29 years we have found Pertronix is the best for Ford tachs!
