I notice there are 3 relays on the diagram and read else were they are a little weird.

I think I'm reading you right. just to clarify, you can eliminate the fuel pump relays from the LS side of the harness if they're included. not the oem side. the bypass still uses the oem relay to turn pump on and off, it just removes the OEM computer's control to reduce power.
you need the LS harness to control the fans, either running a wire(or two) into the fusebox to trigger the OEM relays, or by a separate relay and to the fans.
