i got a 84 c-10 and put some led from fbi rides and cant figure out how to wire them up. i got a green,brown,yellow and lime green wires from stock harness. the tac unit i got has white,red and green wires. i was told not to use the green wire on the tac unit. i cant figure out how to get my turn signals to work they both flash at the same time. thanks any help please
