What wire color and circuit number goes to the EGR Control Solenoid on the 5.0L?

The EGR Control Solenoid uses wire 360 BR/PK (brown/pink) through connector C180, running through C101 to PCM pin 33. It gets 12V on circuit 361 R when the relay is energized.

Which PCM pin controls the Canister Purge Solenoid?

The Canister Purge Solenoid connects through connector C171 on wire 101 GY/Y to PCM pin 11. When the PCM grounds the solenoid, fuel vapors collected by the carbon canister are released to the engine.

What is the wire for the Idle Air Control Valve?

The Idle Air Control Valve (connector C1007) uses wire 264 W/LB to PCM pin 21, with 12V supplied on circuit 361 R when the relay is energized.

What do the AIRB and AIRD solenoids do according to this diagram?

The Secondary Air Injection Bypass (AIRB) Solenoid directs secondary air to the exhaust or bypasses it to atmosphere (wire 190 W/O via C1022). The Secondary Air Injection Diverter (AIRD) Solenoid directs secondary air to the exhaust manifold or catalytic converter (wire 200 BR via C1023 to PCM pin 34).

Where do the Vehicle Speed Sensor wires from the PCM go?

PCM pins 6 and 3 connect via wires 676 PK/O and 679 GY/BK to the Vehicle Speed Sensor (VSS), covered on pages 64-1 and 64-2 of the diagram set.

This document is page 24-2 of a Ford wiring diagram set covering Engine Controls for the 5.0L engine. It shows the power and control circuits for five emission/engine-control solenoids and valves: the EGR Control Solenoid (connector C180, wire 360 BR/PK to PCM pin 33), the Secondary Air Injection Bypass (AIRB) Solenoid (C1022, wire 190 W/O), the Secondary Air Injection Diverter (AIRD) Solenoid (C1023, wire 200 BR to PCM pin 34), the Canister Purge Solenoid (C171, wire 101 GY/Y to PCM pin 11), and the Idle Air Control Valve (C1007, wire 264 W/LB to PCM pin 21). All devices receive 12V on circuit 361 R when the relay is energized. Ground/control-side wires pass through connector C101 to the Powertrain Control Module (PCM) at connector C185. Additional PCM circuits shown include wire 784 LB/BK (pin 42) to the All-Wheel Drive circuit (page 34-3) and wires 676 PK/O and 679 GY/BK (pins 6 and 3) to the Vehicle Speed Sensor (pages 64-1, 64-2). Descriptive callouts explain each component's function, such as the IAC valve's duty-cycled idle control and the canister purge solenoid releasing carbon-canister fuel vapors when grounded by the PCM.
