Import the product-ka_ultimate_sidecolumns.xml file as a product through your product manager.
Open your header template and at the very end add
Code:
<!-- USC header edit start -->
<table width="100%" cellpadding="0" cellspacing="0" border="0">
<tr>
$usc_left
<td valign="top">
<!-- USC header edit end -->
Open your footer template and above
Code:
$spacer_close
add
Code:
<!-- USC footer edit start -->
</td>
$usc_right
</tr>
</table>
<!-- USC footer edit end -->
That is all your template editing done.
Now, go to vBulletin Options > Ultimate Side Columns Options
