There is a plug on the top of the radiator on the drivers side.... What is it?

The previous owner dicked up the entire thing and i need to replace it. So if anyone knows what it is, let me know. It would be appreciated.

OK, just so I am clear here...there is a plug on the top of your radiator on the drivers side? right?

pretty sure its used when installing or removing the radiator, it puts pressure on the mounting bracket below to keep it tight in place.

Its an electrical plug, on the drivers side of the radiator... Its not really on the top of the radiator... Its in the side, at the very top... Ill see if i can get a picture.

2 of em i think
ones coolant temp sensor for gauge not ecu i think
ones aux fan switch, the electrical fan in front of AC condensor
apply power and fan comes on
I removed all of that on mine for weight and cooling and i couldnt afford to make it all work again lol
get the Bently manual!!!
