I don't know which colors went where and I'm away from my car for at least a week due to work... Each board has an input for a left side and right side blinker as I recall. I don't know why they did it that way I only connected 4 wires at each board. You will need to pull out a volt meter or even just a test light would be fine to find which wire goes constant 12v with the tail lights on then find the wire that pulses 12v with turn signal on. The 3rd wire from the 1157 adaptor pretty much has to be ground. So your 4 wires per board should be like is: 12v constant that you will need to run separately. (This one I remember as orange) Turn/brake light (pulsing 12v with flasher or turn signal on) Tail light (constant 12 with tail lights on) Ground (should never show 12v) Sorry can't help more right now.
