barrel key wiring help

[Cheeseman]

found this barrel key ignition in my box of parts for my 81 Yamaha xs400.
How to I go about wiring it into my harness to make it work?

If you have a stock harness, you would remove the old key switch, then run the harness blue and harness brown from the old connector to the white on your new switch. then red goes to red.
