Modified TPL code for my purposes.
Advantages, only show Manufacturer if the manufacturer exists for that product. I also turned off the absolute link to the manufacturers.php and went with the relative link.
Code:
{if $manufacturer ne ""}
<tr><TD align="left" valign="top">
Manufacturer:
</td>
<TD align="left" valign="top">
{$manufacturer}
<font size=1 face=Arial>(Click to get more information about this manufacturer)</font>
</td>
</tr>
{/if}
