Hi guys I'm new here and I can't find anything anywhere on this. 2 days ago I brought a 2018 750 home. I wanted a reverse light so I used the wires in the back that hang there. It worked fine when I did i texted it. I mounted it on and wired it and since then it will not work. It's a 6" led bar. Is there a fuse for those connecters? If I hold the wires on the other one that hangs there the light turns on.
