Here's a shot of the actual bones.  The smaller one outlined in red is the first hip (start bone) the second one in red is the regular hip (second hip)  this is where they are placed for my model.  For your model they will need to be adjusted depending on the geometry and shape of your model.  There's lots of other bones in there but they are just regular rigging and body handles. Now, you can put a peice of geometry inside the model or outside the model named the same as your start hip bone so you can have something to grab with the cursor.
