vB5 uses jQuery UI Autocomplete plugin for autocomplete functionality and it's wrapped in vBulletin_Autocomplete function.

Try this for a start:

var userAutocomplete = new vBulletin_Autocomplete($('.friend_name'), {
    apiClass: "user"
});

There are many other options to vBulletin_Autocomplete. Just look it up in the code.
