I was just looking at my manual and noticed some things. My motor is a 72' but it has some of the same wiring as the 73-76 models. Mine has the 72' key swith/choke assembly, but it has the male/female connections like the 73'-76'. According to the manual mine should also have a green wire that goes all the way to the battery+ terminal of the starter solenoid, but instead the green wire on mine meets up with the red battery cable inside the female end of the connection point. Also the diagram for the 72' does not show a neutral safety switch, but mine in fact does have one. Does the fact that my motor is an anniversary edition have anything to do with this, or would it just have been later in the year and possibly they started incorporating some of the 73' concepts into a few 72' models? I just thought it was interesting.
