so, i am going to modify my 76 750f harness so i can use an ignition switch from a 72 750k. the 76f has a 5 wired switch (red, black, brown/white stripe, 2 browns) and the 72k has a 4 wired switch(red, black, brown/white stripe, 1 brown).
i have also opted to use my 72k handle bar controls. i like the idea of being able to turn my head light on and off.
my question is, and i apoligized if it has been covered, what do i do with the extra brown wire? i have looked at wiring diagrams for the ignition switches, but i am having a hard time figuring it out. do i splice the browns together or figure out which one goes to the headlight(i am figuring one does) and leave it disconnected?
