Ford 5.0L engine controls wiring diagram showing ignition switch, malfunction indicator lamp and clutch pedal position switch circuits.
Part of 1992-1996 Ford Bronco Wiring Diagrams
This document is page 24-7 of a Ford wiring diagram set covering Engine Controls for the 5.0L engine. It shows the power feed circuits into the Powertrain Control Module (PCM). On the left, a Hot-in-Start-or-Run circuit runs from fuse 17 (10A) in the fuse panel through wire 640 R/Y via splice S215 and connector C250 to the Malfunction Indicator Lamp (MIL) in the instrument cluster, then continues as wire 658 PK/LG through C251, C202, the VIP Data Link Connector and C198 to PCM pin 17. A note explains the MIL lights with the ignition ON before cranking, goes off after start, and is turned on by the PCM if a fault develops. On the right, a Hot-at-All-Times feed through the ignition switch (C269, wire 32 R/LB, splice S224, wire 480 P/Y) passes through the Clutch Pedal Position (CPP) switch or jumper, three variants are shown for E4OD/4R70W, manual, and C6 transmissions, continuing as wire 481 GY/Y to C185 and PCM pin 30. Additional PCM circuits shown include 4R70W transmission wires 970 DG/W and 766 BK/LG (pins 5 and 29) and A/C-heater wires 883 PK/LB and 348 P (pins 10 and 43). Cross-references point to power distribution, starting system, ignition switch, cluster, and A/C pages.

Frequently asked questions
- What fuse powers the Malfunction Indicator Lamp (MIL) on the 5.0L engine controls circuit?
- Fuse 17, a 10A fuse in the fuse panel (Hot in Start or Run), feeding wire 640 R/Y. See Power Distribution page 13-16 and fuse panel pages 13-3, 13-9.
- What wire colors connect the MIL to the PCM?
- Wire 640 R/Y feeds the MIL in the instrument cluster; from the MIL, wire 658 PK/LG runs through C251, C202, the VIP Data Link Connector, and C198 to PCM pin 17.
- When does the Malfunction Indicator Lamp light?
- The indicator lights with the ignition switch in the ON position prior to cranking and goes off when the engine starts. If a fault develops in the engine control system, the PCM turns the indicator on.
- How does the Clutch Pedal Position (CPP) switch circuit differ by transmission?
- Manual transmissions use an actual CPP switch that prevents engine startup with the clutch pedal released; E4OD/4R70W and C6 automatic transmissions use a CPP switch jumper instead. All versions receive 12V (start) on wire 480 P/Y at C261 and output on wire 481 GY/Y.
- Which PCM pins are shown on this diagram?
- Pin 17 (MIL circuit, 658 PK/LG), pins 5 and 29 (with 4R70W: 970 DG/W and 766 BK/LG), pins 10 and 43 (without E4OD or 4R70W: 883 PK/LB and 348 P from A/C-heater), and pin 30 (without E4OD or 4R70W: 481 GY/Y start/switch-closed signal).
