Hello, for those who are using the MSD 6al where did you find your ignition wire? Ive found plenty of them but none that stay12 volts while starting. They all drop down to zero. Ive tested it with a constant 12v and it works fine. 

All Z's should have those wires at the ballast resistor location.

 

Here's an example for 1976.  One is black with white stripe, the other is back with blue.  Your year may have different colors.

Ok, i tested that one and it drops to zero but it works. Thanks! Again.
