Perry,
Thanks. That is exactly what I did with the WHITE wire on my earlier car.It worked as a kill switch, and it was well hidden.

Re-reading the MSD manual, I am lead to believe there should be just the two wires from the box coming to the coil. SImple enough.
This time around I was careful enough to install the wires to the correct terminals. It worked !

Now I have to get the tach working, and I am all set. I just need to find out from someone with a similar setup as mine and see how they hooked their tach. There are two wires in the back of the tach, only one wire coming out of the MSD box.
