Ya it sounds like a bad fuel pump. The notorious power splice can affect the power to the pump. I would double check that first. You can find a write up in the FAQ in this section.
To answer your main question the connector is under the hood on the passenger side by the firewall. It is a square type of connector that has a notch on its side. It will just be danging down.
But unless you have a scanner or a code reader that will not help you diagnosing your fuel pump problem.
