Welcome to the forum and congrats on your new bike.
Fairly easy fix. I believe they still use bullet butt connectors. Three wires each side - the extra wire is for running lights. You’ll have to remove the headlight cowl and probably the headlight mounting bracket to be able to properly switch the wires around. While you’re at it, check your clutch spring for proper installation if they mixed up the turn signal wires it might have been a novice doing assembly.
If you have time to take it back to the dealer, it might be a good test of their service. A sign of what you can expect in the future. Cheers
