MSD Digital
Just finished wiring up my MSD digital 6AL ignition control part number 6425 on my stock 73 corvette.
I have stock points distributor and new MSD Blaster coil. Everything is wired up properly. The only thing I have a light grey wire from the MSD that is supposed to go to TACH OUTPUT. Does anyone know where this gray wire is supposed to go. I also have a stock tach.
Any pictures or diagrams will be greatly appreciated.

Just cap it off. It's unneeded.
