Today I pulled off my bumper and grill guard and found this wire with a plug on it. It is right below the passenger side of the radiator.
Anyone know what this goes to??

 

do you have the overhead console with the temp and compass, could be for one of the sensors

 

fog lights that didnt come with that truck? air bag sensor? flux capacitor?

but its not uncommon to see random plugs hanging around most vehicles like that

 

Yeah I have the over head temp gauge but it works (most of the time)
