I've got a 2015 Silverado regular cab. I installed Razir's led tailgate light bar last summer. I decided to keep it on this winter for snowplowing, since it adds quite a bit of extra lighting when I'm in reverse. This week the white wire that connects from the light bar into the left taillight tore apart. And with that, my reverse lights stopped working. I spliced the two wires back together and heat shrunk them. Still.. No reverse lights. I checked the fuses under the hood, and replaced the trailer reverse lights. I also checked the fuse panel under my dash, but I cannot find which goes to the reverse lights. So does anyone know which fuse under the dash are for the reverse lights? And also why I would still not have reverse lights? (Yes, I do have taillights) Thanks
