This is how it's wired, I just don't know if the diode should be flowing electricity towards the LED or away. I think it should let the flow go away from the LED back to the TSD (temperature sensing diode) in the motor which is connected to the 'red' wire (ground) which is also connected on the other side of the LED...
do you have a multimeter? if so, measure the resistance between red and blue wires. measure from both sides also, I think TPD might be another diode, I'm curious to see how they are adding overheat protection. I think they found a really cheap and inaccurate way to do it.
the banded side of the diode should connect to the ground (red wire), the non banded to the 1k ohm resistor. the short side of the led goes to the blue wire, long to the diode resistor junction.
I didn't tear into the led enough to be able to tell which side the red was tied into, but the white and blue wires are definitely tied together on the opposite side of the red. Here is my thinking on this.
The white wire supplys 12 volts into the 1k resistor and then the power goes through the diode into the blue wire which takes the power to the TPD (which I believe to be an on/off thermostat switch) which lets the power go to ground when the winch is running cool. When the winch gets hot, the TPD goes to the 'off' position and forces the power through the LED, lighting it up. Does that logic make any sense to you?

All I see is grubby hands and fingernails...:flipoff2:
Cool stuff, I'm interested to see the final product.
