i just installed a blaster 2 coil and msd 6a in my 85 5.0, and the stock tach nolonger works. is there a way to wire it up with out buying the MSD Tach Adapter. thanks
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
