<VV> Ignitor II update

[Bob Gilbert]

Howdy Folks,
On the few installations I have done lately I used a relay triggered  by 
the positive lead to the coil. The reduced voltage from the ballasted 
wire has triggered the relay just fine. Fused lead from the battery 
triggered by the ignition circuit feeding full battery voltage to the 
Pertronix unit. Worked fine for me and a few others.
