Thanks for the info guys.
I just wanted to know some history behind it. Might be that it was the first model of plug key ignition produced by Tec released for other honda markets, then was adopted for smaller capacity bikes in the USA, as well as the cb750 in 69, but with black plug key.
I have seen recessed switches from smaller capacity bikes with the same early key but with black plug. These have been in the USA.
Hi Conrad, The cream plug in question is the plug on the key itself.
Regards,
Steven.
