Not to get into much detail and debate here, i would like to use the reverse light fixture to mount some 3157 brake lights in there in addition to the regular brake lights already there (Im not concerned about where the reverse lights would go yet).
i dont want them to be turn sigs or running lights. the sole purpose is just to be a brake light.
now, which wire would i need to splice into to get the effect im looking for?
i have a 04 cavi, and i believe the wires that go into the 3157 socket are blue, brown, and black. thanks.
