What connector does this diagram cover?

It covers C202, the Powertrain Control Module (PCM) connector, showing a 104-pin connector face and a table of pin functions for pins 1–34.

Which pins are the Data Link Connector (DLC) circuits?

Pin 13 is circuit 107 (P) Data Link Connector (DLC), pin 15 is 915 (PK/LB) DLC Bus (-), and pin 16 is 914 (T/O) DLC Bus (+).

Which PCM pins go to the Crankshaft Position (CKP) sensor?

Pin 21, circuit 138 (BK/PK), and pin 22, circuit 139 (GY/Y), are the Crankshaft Position (CKP) Sensor circuits.

What wire controls the shift solenoids at the PCM?

Pin 1, circuit 315 (P/O), is Shift Solenoid #2 Control, and pin 27, circuit 237 (O/Y), is Shift Solenoid #1 Control.

Where are the ground pins on this PCM connector?

Pin 24, circuit 570 (BK/W), is Power Ground; pin 25, circuit 57 (BK), is Case Ground; and pin 33, circuit 676 (PK/O), is Case Ground.

This document is a pinout diagram and legend for connector C202, the Powertrain Control Module (PCM) connector on a Ford vehicle. The top portion shows a 104-pin connector face with pins numbered 1 through 104 arranged in four rows, with circuit numbers and wire color codes (e.g., 315 P/O, 658 PK/LG, 570 BK/W, 526 DB/LG) called out around the connector housing. The lower portion is a table listing pins 1 through 34 with their circuit number/wire color and circuit function. Documented functions on this page include Shift Solenoid #1 and #2 Control (pins 27 and 1), Malfunction Indicator Lamp (MIL) Control (pin 2), Data Link Connector circuits including DLC (pin 13), DLC Bus (-) (pin 15) and DLC Bus (+) (pin 16), Crankshaft Position (CKP) Sensor (pins 21 and 22), Power Ground (pin 24), Case Grounds (pins 25 and 33), Ignition Coil #1 (pin 26), Transmission Control Switch (TCS) Input (pin 29), and Octane Adjust Shorting Bar Input (pin 30). Many pins in this range are marked NOT USED. This appears to be page one of a two-part set (companion file C202-b covers the remaining pins). A reader can identify which wire color and circuit connects to each PCM pin for diagnostics.
