I now have two different sizes of emac's power supplies and both have 2 extra pairs of wires, Red and black as well as yellow and black. On the model above they both have 2pin push connectors with wings slimier to a 3 pin fan header on the other one on pair is like that while the other has a different kind of rounded connector. I have never been able to find a manual to explain what they are. the only thing I could think of was indicator lights for if a power supply went bad.
In the G1W2-5760V3V Manual on the last page it is documented:
It seems these are:
The LED connector should be black/blue or red/black/green.
Please compare your connectors with the ones in
