Hi guys - I just picked up a very rough CB125 as a project bike for the fall. There's no key and the kill switch is all corroded. I would like to test the bike for spark and am trying to figure out how to wire the bike without a key or kill switch. Can someone help me decode the wiring diagram?

The main switch is easy enough - Connect the red and black wires going into the ignition assembly.

The headlight control switch is where the diagram has me confused. What wires do I need to connect in order to have the kill switch in the Run position? Is this this (N) setting in the chart at the bottom left? (So: brown + black + yellow/white + yellow?)

My hope is to wire in a 6V so I can test for spark. I will disconnect the ignition wires as soon as I'm done so as not to kill the battery.
