i don't think so i have a digital 6 msd box and i had to get the tach adapter so that my factory tach would work.

if you can find the lead wire for the tach.. then plug it into the side of the box right next to the tach adapter.. but hate to say it.. you MIGHT have fried the stock tach from putting the box on there and coil without disconnecting it.. it fried mine i know that
