What wire color goes from the EGR Control Solenoid to the PCM on the 5.0L?

Wire 360 BR/PK runs from the EGR Control Solenoid (connector C180) through C101 to PCM pin 33.

What connector and wire does the Idle Air Control Valve use?

The Idle Air Control Valve uses connector C1007 with wire 264 W/LB, running through C101 to PCM pin 21.

How are these engine control solenoids powered?

All five components (EGR solenoid, AIRB, AIRD, canister purge solenoid, and IAC valve) are fed by circuit 361 R, which supplies 12V when the relay is energized.

What does the Canister Purge Solenoid do according to this diagram?

When the PCM grounds the solenoid, fuel vapors collected by the carbon canister are released to the engine. It uses connector C171 and wire 101 GY/Y to PCM pin 11.

Where does the Vehicle Speed Sensor connect on this diagram?

The VSS connects via wire 676 PK/O (PCM pin 6) and wire 679 GY/BK (PCM pin 3); its full diagram is on pages 64-1 and 64-2.

This is page 24-2 of a factory-style wiring diagram covering Engine Controls for the 5.0L engine, uploaded to a 1996 Ford Bronco gallery. It shows five emission/engine-control solenoids and valves fed by circuit 361 R (12V with relay energized): the EGR Control Solenoid (connector C180, output wire 360 BR/PK to PCM pin 33), Secondary Air Injection Bypass (AIRB) Solenoid (C1022, wire 190 W/O), Secondary Air Injection Diverter (AIRD) Solenoid (C1023, wire 200 BR to PCM pin 34), Canister Purge Solenoid (C171, wire 101 GY/Y to PCM pin 11), and Idle Air Control Valve (C1007, wire 264 W/LB to PCM pin 21). All control wires pass through connector C101 and terminate at the Powertrain Control Module (PCM) via connector C185. Callout notes explain each component's function: EGR vacuum regulation, secondary air routing, idle speed duty-cycle control, and canister purge operation. The bottom of the diagram shows PCM pin 42 (wire 784 LB/BK) going to the All-Wheel Drive circuit (page 34-3) and PCM pins 6 and 3 (wires 676 PK/O and 679 GY/BK) connecting to the Vehicle Speed Sensor (VSS), referenced on pages 64-1 and 64-2. Useful for diagnosing emissions, idle, and PCM control circuits.
