See the diagram you need

When a diagram explains it better than words can, rx7db links you to the right one.

"My fuel pump isn't priming. Where's the FPR relay in the harness?"

The wiring tool traces the circuit and returns the page you need, so you can follow the actual harness instead of working from a text description.
