when i hooked up mine i followed the diagram for chrysler electronic ign. w/ magnetic pickup which has the little red connect to whatever was connected to pos coil feed. car ran great. after reading numerous posts saying the ballast can and should be bypassed, i just replaced the ballast coil thing in a stock resistor with a large gauge wire. guess what... car still runs great, don't really notice anything but the ign is now full power all the time.
