I have the same controller. UC7051. I see many wires in a wiring harness on this. The replacement that Ihave have has two for power that go to the power source, 1 for fan and 1 for light. It does not have the reverse function that my fan has, so that wire can be left out. How do I hook up the wires? Which wires do I use and which ones I do not use. I am comfortable with a multimeter.

What is a UC7051?

This should be of some help. https://docs.google.com/document/d/1vwDo5aTinmWJTimjZc_pZNAtPHza5vNNhGO-agFZJAA/edit?pli=1
In most fan light units blue and white go to the light kit while black and white go to the fan
