This is about the best I can do as they are really small. The white wires are power going to t/s switch and overhead cab brake light then it's yellow and green for tailgihts from t/s switch. Also check at rear of frame for ground for all lights they get rusty, dirty and loose contact. Try that first. Also ther eis a circuit board that goes bad in tailights that is available at auto parts
