we just used the hole wiring harness from the zx9r. we just ran the wires where they needed to go IE. headlight plugs into the trailtech bullets. then then tail light wires to the rear, and make sure you have the cdi and rectifier grounded or your going to be chasing hell, and make sure you have the key ignition because we didnt have ours and we didnt have spark then it dawned on us. kawasaki and the shitty anti theft LOL im not sure how yamaha is...
