A really great member of the teener community called last night
he has done more good things for more people, but last night had a question

It was around trying to get his tach to work on his -6 conversion

I remember many threads about not requiring a MSD tach adapter, but couldn't find them in my searches. Can anyone point me along or offer their knowledge to help out ?

specifics: 2.7/6
CDI died a few months ago. MSD was installed, and car runs well. Tach is now not working however. He is running an MSD optical pick up (white wire) and using the wiring instructions provided. He is not running the tach adapter and it was my belief that it may not be required?

thanks in advance all!

I use an Autometer tach, and it's connected directly to the tach output on the MSD.

IIRC, going from a 4 to a 6, the original tach from the 4 will not work with a 6 engine so you need to replace it anyway.
