Want to say Thanks to Randy for the awesome write up. I would have never guessed I could get to this wire like this But I did!
If you picture the fanbox like a clock, the wires you need are at 7 and you should be going in between 10 and 11.
I used the endoscope to see the 2 wires, pulled the ground back and wiggled the power wire off the resistor pack, wow what a surgery, Expert level only!
My connector was ok, and my wire was very short, barley makes it out of the hole with the connector still on, not sure how you were able to have enough to splice. Either way I can just put a male connector in there and begin my wiring upgrade process now.
I modified the needle nose a bit
If brute force is not working you're not using enough.
