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

A 20A fuse in the engine compartment fuse box feeds wire 37 (Y) to the fuel pump relay (see page 13-12 for the fuse box).

What wire color and circuit is the fuel pump relay output?

Circuit 361, red (R), which branches to the engine controls, MAF sensor (5.0L only), E4OD and 4R70W transmission connectors, and the PCM (pins 57 at C185).

Which relay is Bronco-only on this page?

The 4 WABS Relay #2, fed by a 30A fuse through wires 532 O/Y and 534 Y/LG, is noted as '(BRONCO ONLY)'.

How does the inertia fuel shutoff switch connect in this circuit?

Via circuit 238 DG/Y from the fuel pump relay through splice S139 and connectors C202 and C271 to the inertia fuel shutoff (page 49-2).

What connector links the PCM to the diagnostic connector?

Wire 926 LB/O runs from PCM pin 22 to connector C198, the VIP Data Link Connector.

This document is page 13-6 ("Power Distribution, Gasoline") from a Ford factory wiring diagram set, labeled "94" and "GASOLINE." It shows power distribution from the engine compartment fuse box for gasoline engines. A 30A fuse feeds the anti-lock brake circuit via wire 532 (O/Y) and 534 (Y/LG) through the 4 WABS Relay #2 (noted as Bronco only), which powers the 4 WABS Control Module (wire 539 PK/LB via connector C119) and the 4 WABS Pump Motor (wire 533 T/R via C122). A 20A fuse feeds wire 37 (Y) to the Fuel Pump Relay, whose output on circuit 361 (R) branches through splices S136 and S124 to Engine Controls (pages 23-1, 24-1, 25-1, 26-1), the Mass Air Flow (MAF) sensor via C130 (5.0L only), the E4OD transmission via C110/C1048 (wire 912 W/R), the 4R70W transmission via C1049, and the Powertrain Control Module (PCM) at connector C185 pins 57. Wire 926 (LB/O) connects the PCM to the VIP Data Link Connector (C198), and wire 238 (DG/Y) runs through S139, C202, and C271 to the Inertia Fuel Shutoff (page 49-2). Wire colors, circuit numbers, connector IDs, and cross-reference page numbers are given throughout.
