My manual doesn't include a diagram for the 94 but it has one for the 98. Hopefully it will help.
Their is a six lead connector that supplies all connections to the gas tank on the side of the cavity of the car under body that holds the gas tank. The gray lead is power in from the fuel pump relay. It supply's the 12v. to the fuel pump.
Their are 2 black leads in this connector. One lead goes to ground and supplies ground for the fuel pump, a second black lead becomes both a second and third lead. They connect together on top of the gas tank. They are return leads for the fuel pressure sensor and the fuel level sensor.
The forth lead is purple. this lead is source lead (the other connection) to the fuel level sensor.
The fifth and sixth leads are dark green and tan. The tan is a 5v. supply to the fuel pressure sensor and the dark green is the pressure sensor input to the pcm.
Hope this is helpful.
