A trailer tongue extension assembly that includes a tubular trailer tongue, a removable extension, a first electrical connector disposed within the trailer tongue and a second electrical connector disposed within the removable extension. The first and second electrical connectors engage and disengage as the removable extension is installed or removed from the trailer tongue. A tongue pin is inserted either through registered holes in the tongue and the installed extension, or through aligned holes in the trailer tongue. A lock assembly secures the pin in the holes to, respectively, lock the extension on the trailer tongue or prevent the extension from being installed in the trailer tongue.
