What size fuse feeds the fuel pump relay in this power distribution diagram?

A 20A fuse in the engine compartment fuse box feeds the fuel pump relay, which outputs circuit 361 R and circuit 37 Y going to the engine compartment fuse box on page 13-12.

What wire color is circuit 361 and what does it power?

Circuit 361 is Red (R). It powers the engine controls (pages 23-1, 24-1, 25-1, 26-1), the MAF sensor connector C130 (5.0L only), the E4OD transmission via C1048, the 4R70W transmission via C1049, and PCM connector C185 pins 57.

Which relay is used only on the Bronco?

The 4 WABS Relay #2 is marked "(BRONCO ONLY)" and is fed through a 30A fuse; related circuits are 532 O/Y, 534 Y/LG, 533 T/R, and 539 PK/LB to the 4 WABS control module and pump motor.

What circuit connects to the inertia fuel shutoff switch?

Circuit 238 DG/Y (dark green/yellow) runs through splice S139, connectors C202 and C271 to the Inertia Fuel Shutoff, covered on page 49-2.

What circuit feeds the VIP data link connector?

Circuit 926 LB/O (light blue/orange) feeds the VIP Data Link Connector at C198 and also goes to PCM (C185) pin 22.

This document is page 94 of a Ford wiring diagram manual, section "13-6 Power Distribution, Gasoline." It shows the power distribution circuit for gasoline engines, tracing circuit 361 (Red) from the engine compartment fuse box through a 20A fuse and the Fuel Pump Relay, and through a 30A fuse feeding the 4 WABS Relay #2 (noted as "Bronco Only") for the anti-lock brake system. Circuit 361 R distributes power via splices S136 and S124 to the Engine Controls (pages 23-1, 24-1, 25-1, 26-1), the Mass Air Flow (MAF) sensor via connector C130 (noted "5.0L only"), the E4OD transmission via C1048 (with a "With E4OD Transmission" callout and connectors C122/C110 carrying circuit 912 W/R and 533 T/R), the 4R70W transmission via C1049, and PCM connector C185 pins 57. Circuit 926 LB/O feeds the VIP Data Link Connector (C198) and PCM pin 22. Circuit 238 DG/Y runs through splice S139 and connectors C202 and C271 to the Inertia Fuel Shutoff (page 49-2). Circuits 532 O/Y, 534 Y/LG, and 539 PK/LB serve the 4 WABS control module (C119 pin 29) and pump motor. Wire colors and connector/pin numbers are labeled throughout.
