I bought a street glow optx 49" tailgate strip (red led lights that mount under the tailgate) and im having trouble wiring it. I dont have a trailer wiring harness so I am going to hard wire it like the directions say. I kind of understand what to do, but there are so many wires running to each taillight and some of them are the same color. I need to figure out which wire to attach the left turn signal to, the right turn signal, the running lights, and the ground. All the wires are wraped in the black plastic so I cant follow them. Has anyone had these issues or can anyone help me?
