What is pin 1A on the Ford Probe PCM connector C248?

Pin 1A is circuit 94 (BL/R), Keep Alive Power (annotated 'Constant' by the uploader).

Which C248 PCM pins are used for the Data Link Connector (DLC)?

Pins 1D (712 W/R), 1F (711 LG/R), and 1I (715 R/W) are all Data Link Connector (DLC) circuits.

What do the asterisks mean in the C248 pin table?

A single asterisk (*) indicates the circuit applies to automatic transaxle vehicles; a double asterisk (**) indicates manual transaxle.

Which pin is the PCM module ground on connector C248?

Pin 1T, circuit 914 (BR), is Module Ground.

What C248 pin carries the vehicle speed sensor signal?

Pin 1M, circuit 369 (GN/R), is the Vehicle Speed Sensor Input (+).

This scanned page presents Ford Powertrain Control Module (PCM) connector pinout diagrams and tables, apparently from a Ford Probe wiring/EVTM manual. The main, clearly legible section covers connector C248, showing the PCM connector face with circuit numbers and wire colors, plus a complete pin table (pins 1A–1V) listing circuit numbers, wire colors, and functions such as Keep Alive Power (94 BL/R), PCM Power (702 R/BK), Start Signal Input, Data Link Connector pins, MIL output, Distributor Ignition, A/C Relay Output, Vehicle Speed Sensor Input, Power Steering Pressure Input, Brake Input, Park/Neutral Position Input, Reduce Torque signals, Closed Throttle Input, and Module Ground. Footnotes distinguish automatic (*) versus manual (**) transaxle circuits. Two additional rotated tables cover connectors C246 (module grounds, CKP/G/CID signals, VRIS solenoids, fan controls, EGR solenoids, IAC, fuel pump relay, injectors 1–6) and C247 (barometric pressure, VAF, HO2S inputs, ECT, TPS, reference voltage, EGR position, IAT, knock sensor, canister purge, condenser fan control). Handwritten notes annotate reference voltage/TPS, VAF signal, IAT, and sketch left-front and right-front sensor/relay circuits with wire colors (R/BK, BK, BK/BL). Useful for diagnosing PCM wiring, sensor circuits, and pin functions.
