I was pulling out my manifold on the driver's side to install my LT headers when I accidentally broke part of the plastic of some wire connection that sticks into the side of the Head on the Driver's side. Anybody knows what it is? It some kind of hex bolt with the wire connection. It looks like I can unscrew it from the head to replace it.

 

Coolant temperature sensor that runs to the gauge cluster.

 

yes, you can just replace it
