odd power supply connector

[cyraxote]

Just replaced the 280-W PSU in my Lenovo desktop with a 550-W PSU from Antec. The old PSU had a little connector with two wires and two pins that connected to a light in the case. The PSU end of the plug says "P9" on it, and the case side says YC and a number I can't make out.

The Antec power supply is modular, so I may be able to get a cable from them for this light, but I don't know what to look for or ask for.

I took some pictures of both connectors. Case end:

Any ideas or advice would be appreciated.

Thanks.

I'd say it could be used for RPM monitoring, but that could be achieved with two wires, not three. So I don't know what it is.

It is two wires. And I know that it powers a light in the case. So I know what it's doing, I just don't know what to call it so I can order a cable.

Link to picture of the fix. However, I would use a 4-pin molex extension for the splice, so I did not have mess up the one from the power supply.

Yes, I've seen that post. In fact, I posted the last message, asking for more details. I've not done this sort of thing before, so I want to make completely sure that I understand it before I do anything.

Something like this might work for you:

Use the "5V" side and a small pin to rearrange wires if you need it.

Actually NM it looks like you have a fan controller of some sort

--edit-- below seems wrong---

It looks like it just powers a pair of LEDs on the front panel. I suspect that you might have a ground and 2 5V leads, one makes it blue, the other red and both = purple.
