I have been looking everywhere to find the fuel pump relay location. I thought it was under the dashboard on the passenger side but had no luck there unless I'm looking at the wrong relays. It's not under the driver's side and it's not under the hood. I was just wondering if anyone could tell me where it is or what wire it is connected to. Please and thank you.

The fuse pump relay is located at the right fuse and relay box. It should say in the fuse panel cover. In the diagrams below shows the location of the relay though don't pay attention to the A marking that is for the HVAC system. I can't find the exact location but here is the relay in the engine wiring diagrams. Check out the images (below). Please let us know what happens.

I did find the fuse to the fuel pump relay under the hood but I'm still not able to figure out where the main wire to the relay is. I thought the fuel pump relay would make a click noise when the car is powered before starting. I'm trying to splice a hidden switch into the fuel pump relay as an anti-theft device and in order to do so I need to find the main wire to the fuel pump relay. I think I found it, but I don't know how to test if it is the correct relay. I thought you could test with volts, but I have 4 wires connecting to the relay and 3 of them are constantly 12 volts while only 1 is not. Are the wires colored and is there a better way to test to find it? If not I totally understand, and the diagram above did help me find the location, I think I just need to know how to test it. Thank you! If pictures would help let me know.
