If you take off the 'tank" and the air cleaner you can see the connector blocks for the switch. The red one handles the police only switches. As the wires are no longer used you can cut into the harness side of the connector ,give yourself say 75mm to play with, cut and shut which ever you want, colour diags available for the switches.here somewhere.
I have soldered wires to suit and use heat shrink to finish, often use two sizes, one inside the other. A little butane blue pencil flame works well.
