What fuses power the engine management circuits in this diagram?

Maxi Fuse I 30A (hot at all times), Maxi Fuse U 20A (hot in run or start), Maxi Fuse O 20A (hot at all times), and Fuse E 15A (hot in run).

What wire colors go to the fuel pump relay and fuel pumps?

The fuel pump relay is fed YEL (from Maxi Fuse O 20A) with LT BLU/ORG and RED wires; the fuel pumps are fed RED OR BRN/WHT and BRN/WHT, with ORG wires and BLK grounds.

Which module does this diagram show, PCM or EEC?

Both: the main connector is labeled Powertrain Control Module (1993-95) and Electronic Engine Control Module (1992); a separate Powertrain Control Module connector handles transmission control wires on pins 52, 42, 19, 38, 53, 41, 32 and 55.

What ignition module is used on the 1992 models?

The 1992 models use the TFI Ignition Module, while 1993 models use the Ignition Control Module, both shown in the same box on the diagram.

This is page 12-43 from Chapter 12 (Chassis electrical system) of a repair manual, showing the engine wiring diagram for 1992-93 Ford F-Series and Bronco 5.0L (VIN N), 1992-94 F-Series and Bronco 5.8L (VIN H), and 1995 F-Series and Bronco 5.8L (VIN H) engines. The diagram is centered on the Powertrain Control Module (1993-95) / Electronic Engine Control Module (1992) and shows numbered connector pins with wire color codes for all engine management circuits. Components depicted include the PCM/EEC power relay, fuel pump relay, ignition coil, distributor, TFI ignition module (1992) / ignition control module (1993), spark plugs, eight fuel injectors, IAC valve, EVAP canister purge valve, EGR control solenoid, secondary air injection bypass and diverter solenoids, inertia fuel shut-off switch, tank select switch, dual fuel pumps, knock sensor, power steering pressure switch, EGR valve position sensor, throttle position sensor, MAP sensor, intake air temp sensor, engine coolant temp sensor, vehicle speed sensor, heated oxygen sensor, and the VIP data link connector. Power feeds are identified: Maxi Fuse I 30A and Maxi Fuse O 20A (hot at all times), Maxi Fuse U 20A (hot in run or start), and Fuse E 15A (hot in run). A reader can trace any engine sensor or actuator wire by color and PCM pin number.
