A big THANK YOU to raceman62race for providing this PDF document for the Yamaha Passing Lamp installation. These are the original instructions from Yamaha that many say do not always come with the lamps.
Most folks here would recommend that you supplement these instructions by adding a relay. Adding a relay will prevent the extra load of the lights from passing through your ignition switch and also isolates the passing lamps from your normal light circuit which would prevent your losing your headlight in the event of a short circuit within the passing lamps.
Here is a simple diagram on wiring a relay for the lamps.
