MSD installed..where does the tach wire go?
This is a '76 car with a '79 3.0
Until today I've had the old points dizzy with a mag dizzy gear on it to make it work but it was turning the wrong way. Swapped out the points dizzy and 3pin CDI for a mag trigger dizzy & 6AL MSD. All done and running good. Just need to know where to connect the MSD tach output to. Any takers?

Don't know if this helps as application was for a 6pin CDI conversion:
A short lead was made to run from the Tach output on the MSD unit and plugs into the 6 pin connector at terminal TD, no adapter is necessary Regards, Jason aka The Freak!

Plug that black/purple tach wire right into the tach terminal at the end of the MSD box.

Either I'm looking right at that black/purple wire and not seeing it or this wiring I have is among the parts that have been stirred up on the car.
BUT! I just made a lead and ran it between MSD and old 3pin connector and WAHLAH! My tach is back in the race! Thanks Steve~ Thanks Jason~
