Note 1: Up to October 64 the wires going into the fan motor may both have been black. Because of the 2-way bullet connectors these can be connected either way round. With the later fan motor with the differently coloured wires from the motor the fan gives a vastly superior performance one way round compared to the other, try both ways. With the earlier motor it should make no difference.
Note 2: Before 1970 the wire from the switch was Green with a Brown tracer. From 1970 it was Green with a Yellow tracer.
Note 3: From 1971 for the remainder of chrome bumper production and all V8s the heater fan (and wipers and electric washers) were powered from the accessories position of the ignition switch via a white/green to an in-line fuse under the fusebox, and then via a green/pink.
