2000 LW2 unknown connector broken
 

I recently bought a 2000 LW2 off of a family member, just serviced. I’ve been doing small repairs here and there. I was cleaning my engine bay when I noticed what looks to be a disconnected sensor wire coming from the fan. The connecting bit is broken. My car has had no issues starting or running. I turned the engine on to see if it was related to the coolant temp, gauge was moving so it’s not coolant. I just need some help identifying it or the part number so I can replace it. There also seems to be a bit of melted plastic at the base of the connector, wondering if I should secure it to prevent future damage. If you can, shoot me a direct email at rhysdavison06@gmail.com

That connector is not there on my 2002 LW300, however it is there on my 2000 LS2 parts car. It is the power connector to what appears to be be the heater circulation pump seen lower in that photo. My 2002 has a heater circulation pump on the back side of the engine.
