If it's a schematic your after, go to, autozone.com, and sign up for free to get access to parts info & prices, as well as repair manuals/info. When signed up, pick your year, vehicle etc, then click on repair manuals & go to chassis electrical, then wiring diagrams, and scroll down to Figs. # 43 & 44. All info you need should be right there.

The ECM tells the fuel pump to come on. You can get a circuit breaker from most parts stores, and many stores you can get a repair manual for $20 that will have a schematic in it.
