Okay, I know this has been covered before but I would appreciate it if someone could help me out. I recently junked the factory FoMoCo box and installed a MSD-6al in my SPF (#1114) to get the rev limiter chips. I hooked everything up and it works great, but I can't seem to figure out how to hook up the tach...
Not having a tach is painful so I am hoping someone can walk me through the procedure.
Thanks,
Mel
