Anyone know how to convert this to one of those replacement on Amazon where there is just 2 wires? I can't seem to wrap my head now to replace it.

The controller is failing and doesn't start the blower anymore, sometime holding the test button and turning the knob might get it to spin for a bit but then stop. If I plug the blower directly to the aux plug, I think it bypass the fan controller and it working perfectly fine.
