Hello All,
Question: Does anyone out there use a Holley commander 950 EFI ?
What do you use to send the RPM signal to the Commander ecu ?
Did you ever use the coil (-) yellow wire for the rpm signal to the Holley ?
thanks for reading !

You know, I really don't remember how I did the one in my one V8 Vega, but it has an MSD 6A box, and I remember it used the tachometer feed wire terminal on the side of the box.
For points, I would think that signal would come from the negative side of the coil.
The fellow that runs the EFI department at Holley, Doug Flynn, should be able to help as well. Maybe not for some of his techs, they are too young to know. There should be some sort of wiring diagrams available on the net as well.
I know I would use the C950 EONS before a FiTech/Sniper junker.
