IF that small RED wire on top of the coil is connected to the "-" negative terminal then it goes to the distributor stud (where you have a missing/broken wire).
The GREEN wire on the coil should be on the "+" terminal and should go to one side of the Ballast Resistor AND down to the starter solenoid "I" terminal as Jerry said. This is the resistor by-pass wire that puts full battery voltage on the coil while cranking the engine. The other side of the Ballast Resistor goes the the key switch.
