   Does the factory tach work ok with a MSD6AL? Thanks for any help.

   It should, just make sure you connect it to the tach output on the 6AL box, and not the coil.

   Yes
   
   I tested both my dash & hood tach on the dyno that way.:TU:
   
   Larry is right though, the tach led goes to the MSD.:bglasses:
