You would need to access the junction box on the front forks, which is a real rat's nest of wires. Find the wires coming out of the existing headlight, and trace them down to where they plug into the same colored wires in the junction box. Disconnect the old wires, install the new headlight, and connect the headlight wires to the corresponding wires in the junction box.
So basically.. get new headlight remove old wires from box, install new wires. And put back together.
Sounds simple enough. Do I need anything other than the headlight? Like I said 0 experience with wires. I figured I’d need to solder wires together or something (very confused).
And thank you yet again for the amazing help! How’d you get to know so much about rebels?
