It depends but most likely there are no changes to the bike. Whether your trailer plug is getting power directly from the bike's harness or you have an isolation relay setup, so long as the current directionals work correctly, the addition of the LED trailer lights should work correctly.
You all set with the five wire hookup on the trailer (ground, running lights, all brake lights, left directional, right directional)?
