They're located on the firewall, under a plastic cover.  You'll need to connect a positive wire off the battery block.  I've attached a clickable thumbnail below, colors are listed on that diagram.  This is a page from the electrical troubleshooting manual (ETM) - check it out.  You can download it from here.
