lol so this horn is infact hard to wire , I can't seems to figure it out lol has anyone been able to hook this horn up to their bike ? other than a 2018 tomos. here is a picture of my wiring and my diagram , as for the 2018 horn it looks like it requires a ground and I have grounded and still no horn , all I get is a vibration or if I press on the plate of the horn it makes a sound.
PS: the red wire is for the horn switch and yellow is the power. I've also replaced the yellow with ground and still nothing
