A/C Gone and Runnin HOT...Wire Culprit?

[Starwood]

Hey Fellas -

I recently had to put in a new carb gasket (it was whistling) and during the process, it looks like this wire came loose (in attachments).
I can't seem to find where it was connected - and since I changed that gasket and reset it on intake - no AC - and she was running hotter than hell near 210 on a very quick trip.

It looks like some kind of sensor or relay. Sorry if this is a stupid question, but this 70 is new to me and I've never seen this device on any of my past SBC's....

Please send some advice if ya think this is related and know where this might reconnect.

Thanks Tons
