I have an 1978 R100/7, nothing fancy.

My question is this. I want to disable the "always on" feature of the headlight, and put a switch in - similar to the way my older /6 had the set up. I want the light to come on only when I turn it on, but not on all the time. I also want the headlight "flash" feature to work all the time. Right now, when I turn on the key, the headlight comes on, and stays on even when going through starting. I am sure this pulls power from the starting process.

Has anyone re-wired for this. I think it is a simple matter of wiring in a switch on a power line that runs from the headlight key switch, to the headlight relay. If I am right can someone confirm?
