The Maps API V3 doesn't currently support KML overlays. It is a planned feature, however.
Please try this short example that I use in OpenLayers, a JavaScript map library for expert programmers.

<script type="text/javascript">
var map;
function init() {
// Create the map object
map = new OpenLayers.Map('map');
// Create a Google layer
var gmap = new OpenLayers.Layer.Google(
"Google Streets", // the default
{numZoomLevels: 20}
);
// Add layer to map
map.addLayer(gmap);
// Zoom to Kuala Lumpur, Malaysia
map.setCenter(new OpenLayers.LonLat(101.686855,3.139003), 13);
}
</script>
</head>
<body onload="init()">
<h1 id="title">My OpenLayers: Google Layer</h1>
<div id="map" style='width: 700px; height: 700px'></div>
</body>
</html>
Notice that the google-maps-v3 is forced to be center. As you can see in the following codes I made:
map.setCenter(new OpenLayers.LonLat(101.686855,3.139003), 13);
The LonLat is located in Kuala Lumpur. Bear in mind that it is completely different from your schooldays geography subject, as longitude is x-coordinate. and latitude is y-coordinate. Please refer Cartesian coordination principle.
Good luck.
