RM250 1976 RM 250 Wiring diagram Needed

Hi everyone I'm new to the group and I'm from Minnedosa MB Canada and I just purchased a 1976 RM 250 and the coil is missing. So my question is where do all the wires go because the CDI is connected to the stator with 3 wires but there is one more wire coming from the stator that I'm not sure about and then a few more wires coming out of the CDI that I'm not sure about so anyone with any sort of knowledge about this your help would be greatly appreciated as I can't find anything at all online about wiring this old of a motocross bike....thanks in advance
