hey i got a msd 6a for cheap and im reading the manual. It says that some cars may have issues with the tach and such and may need additional parts. DOes anyone with experience know if ill need anythign else and if so what?

Also when it comes to the distributor part of the connection what do I do?

 

here is a link to a write up on "how to's".
Crane HI-6 wiring is the same as MSD. I used this myself.
