I purchased the 55 rear tail lights from a vendor, all of them have the same LMC, Classic Chev, Brothers etc.... They are the led's. They came with a pigtail. The wiring is pretty simple the female end that is on the light itself has 2 holes 1 for running lights and the other for turn, brake. My question is how does the connection go? the male end is just wire ends? It's like the pigtail is wrong but they are all the same from the pictures. I went to auto parts and hardware looking for a match and no luck. If anyone has the same lights can you enlighten me. My truck is a 51 chevy 3100. I like the look of the 55 lights better so i got them.
