Where is the connection located for the factory antenna? (on GMT900 trucks)

Mine is behind the glove box lid. I open the glove box up, then in the upper right corner there is a plastic tab that pushes in. That allows the glove box to drop down and gives me access to the XM radio box and the antenna plug.
