Wire accidentally ripped out when replacing power supply.

I am replacing the power supply to my iMac. I could not disconnect the tiny plug with the thin wire, I asked my son to help (why!) I told him not not pull the wire, but guess what, he pulled out the wire from that tiny plug.

The wire in question is the power supply temperature sensor in step 12 of the replacement guide.

What do I do now? Is there any way of soldering it back in or purchasing that part? Everything else went fine with the disconnection. I just can't afford to buy a new Mac.

I did kinda the same thing when I replaced the mother board, the heat sensor for the Graphics card broke into pieces when trying to unplug from the old mother board, ah ha, there was another connector to the heat sensor for the cpu I think, so I clip it off, and soldered the new connection but forgot which wire went where so when it was all back together the hydro cooling fan spun at high speed because the machine was not getting feedback, so I took everything apart again and switched the wires and plug them in (the connector only goes in one way), not its all working like normal all 4 leds are on it must be ok. I did have one of the ram chips go bad in this mac even though the system report said it was good. Its a 2008 24 inch Running El Capitan with no problems and only one 4GBs of ram. So I am pretty happy.
