Light green (LT GRN) shown on page 36 (fig.18 backup lamps circuit) & 42 (fig. 21 exterior lamps circuit 3 of 3) (to the trailer connector) is your positive for the reverse lights.

Which wires do you splice to in order to hook up rear roof markers. I want them to come on when my normal lights at night come on. Like jay035 I see 4 going to the taillight. But which color turns what on?
