Lou,

I have always been concerned with the question "will improper connection damage the new tach"?

Our car has an auto meter tach and its instructions call for normal hookup to the negative coil lead (which I did and works fine), unless you are using a multiple spark box, i.e., MSD, for which it shows on the schematic where to hook that into the MSD box. For just a hotter aftermarket coil it does not show any different hookup than the neg lead. I think the reason it has a different connection for the MSD is simply because the MSD delivers multiple sparks. My experience with basic electronic type ignitions is that there is still only one spark and therefore no real change in the reading by the tach of the revolutions.

Don't quote me on this, but I'd think using the same neg terminal on the new coil would be the place to hook to, unless you have some literature with the dist/coil conversion that tells you different.

Good Luck and let us know,

Neal

PS Thanks to Dan McClain for this website - nice place!!
