The other side of the ballast is also connected to the + side of the coil. The negative side of the coil has only one wire and that is the green wire from the module.
BALLAST RESISTOR: MAKE SURE that you have the proper ballast resistor or resistance wire installed. For 1966 & under years GM cars, the resistance across the ballast resistor or resistance wire should be 1.8 ohms. For 1967 & up year GM cars, the resistance across the ballast resistor or resistance wire should be 1.3 ohms.
