We do not have a diagram we can provide for this wiring question. This is a common question and we would be happy to explain, and help you get the lights working. Please feel free to call us at 877-850-7587 and ask for Mike or Todd. FYI.., the yellow wire in the 7-way plug and harness is dead, so that is correct from the factory. The problem is most likely a power source from the tow vehicle, which you wouldn't be aware of the blown or absent fuse unless you needed these light to function. The other lights (Clearance, Brake/Turn) will continue to work even if this auxillary circuit is not energized. Call us, and we can clarify for you and help you get these lights working.
