Unknown connector
 

Can anyone tell me what the connector is in the photos attached? It’s located in front of my radiator and behind the grill. I have a 2008 Nissan Frontier SE 4x4 V6 4.0L and have been having problems with my radiator fan running too much. It starts running when my gauge shows normal operating temperature and does not shut off until I turn the engine completely off. No leaks, overheating, and truck runs well. Just trying to figure this out. Thanks.
