but i think that the "blue wire" is gronding out somewhere so shouldn't i run i new wire to the tach and to the computer??? so wouldn't i run a wire from the MSD box to the computer and to the tach? if so will the msd signal be strong enough to power a tach, a computer, and the external coil?????

 

The MSD tach lead only needs to feed the ECU and tach, the MSD box takes care of the coil.

 

oh yeah i forgot, so do you know what wire it is on the computer? and on the gauge wiring pods?
