Have a msd 6al box on my 69, hei dist, with accel super coil in the lid, the dist does not have the tach hookup due to the super coil, where would i be able to pull a tach lead off the system. dont have paper work on the 6al. thanks

There is a tach output terminal that takes a spade connector on one end of the MSD box. I used it in my 69 with a factory tach and it worked great!

Thanks Larry, I was wondering about the factory tach as well.

Yep. I use that outlet for the tach signal to my FI computer.
