Hi all. Trying to get some of this rats nest, errrr I mean wiring figured out. I have the headlight working and some lights come on in the speedo. My current question is the back blinkers. I have 5 wires. The brown appears to be ground and goes to both lights. The yellow on one side and orange on the other I think are the positives. The blue and green go to the middle light. Is the middle light a brake light?
