So the Fc i got has that wire disconnected and its tucked under the passenger fender.
Any idea why it would be disconnected?

 

What color is the wire?

 

I'm going to guess you're referring to the water level sensor. It makes a terrible beep when the water level is low. Many lazy people ground the wire to prevent the noise. Also shady sellers ground it because it can be a warning to a motor ingesting coolant and needing a rebuild. The wire should be BN if memory serves me correctly. I suggest connecting it properly.

 

I will deff put it back on then. I dont mind beeps lol. But then if coolant got ingested wouldnt that make some nasty clouds?
