What connector does this diagram cover?

Connector C248 of the Powertrain Control Module (PCM) on the 2.5L engine, a 34-pin connector.

Which PCM pins control the fuel injectors?

Pins 5 through 10: pin 5 = injector #1 (705 R/W), pin 6 = injector #2 (706 BL/W), pin 7 = injector #3 (707 BR), pin 8 = injector #4 (708 R/Y), pin 9 = injector #5 (709 W), pin 10 = injector #6 (710 W/BK).

Which pins are grounds on C248?

Pin 27 (65 BK/R), pin 32 (64 BK), pin 33 (63 BK), and pin 34 (69 BK) are all listed as Ground.

Is pin 17 the same for manual and automatic transmissions?

No. Per the legend (* MANUAL, ** AUTOMATIC), pin 17 is NOT USED on manual transmission cars, but on automatics it is circuit 702 (R/BK) Power.

Which pins connect to the crankshaft position sensor?

Pin 15 (circuit 727, GN) and pin 16 (circuit 728, BL) are the Crankshaft Position Sensor circuits.

This document is a connector pinout reference for connector C248 of the Powertrain Control Module (PCM) on a 2.5L engine (per the album context, a mid-1990s Ford Probe with the 2.5L V6). It shows a face view of the 34-pin PCM connector with wire circuit numbers and color codes labeled around the connector body, followed by a two-column pinout table listing each of the 34 pins, its circuit number and wire color, and its circuit function. Covered circuits include PCM power (pin 1, 702 R/BK), heated oxygen sensors (pins 2–3), idle air control valve (pin 4), fuel injectors #1–#6 (pins 5–10), keep alive power (pin 11), diagnosis (pin 12), data link connector (pin 14), crankshaft position sensor (pins 15–16), EGR duty solenoids for vent and vacuum (pins 18–19), EVAP canister purge valve (pin 20), distributor (pin 21), EGR check solenoid (pin 31), and multiple grounds (pins 27, 32, 33, 34). A legend distinguishes manual (*) from automatic (**) transmission variants, notably pin 17, which is NOT USED on manual but is a 702 (R/BK) power feed on automatic. Several pins (13, 22–26, 28) are marked NOT USED.
