What wire colors go to the fuel injectors on this Probe PCM diagram?

Left injectors #2, #4, #6 use 706 BL/W, 708 R/Y and 710 W/BK to PCM pins 24, 25 and 26 via connector C1010. Right injectors #1, #3, #5 use 705 R/LG, 707 BR and 709 to PCM pins 27, 28 and 12 via connector C1011. Injector power feed is circuit 701 W/R from connector C149.

How does the knock sensor connect to the PCM in this diagram?

The knock sensor (KS) connects through connector C138 with a shielded circuit; signal wire 761 W goes to PCM pin 7 at connector C247, and the shield is grounded via 65 BK/(BK/R). A callout states it sends a signal to the PCM to change timing to control engine knock.

Where do the PCM grounds go on this diagram?

PCM ground wires 60, 61, 63 and 64 BK route through splices S125 (auto) / S220 (manual) and S126, and 65 BK/R / 65 BK/BL route through splice S211, all reaching grounds G105 and G106 via joint connectors C106 (see grounds pages 10-9, 10-10, 10-11).

What does the diagram say about how the fuel injectors work?

A callout explains: the injector is a solenoid actuated valve; as the solenoid is energized (pulsed), fuel passes through the injector into the engine, and the longer the pulse, the greater the amount of fuel.

What circuit feeds the headlamp/daytime running lamp branch shown here?

Circuit 261 W runs through splices S277 and S276 to PCM connector C248 pin 15, referencing Headlamps on page 85-1 and Daytime Running Lamps on pages 97-1 and 97-2.

This scan is one page of a multi-page powertrain control module (PCM) wiring diagram, uploaded as "94 ecu page 2" for a Ford Probe. It shows the fuel injector circuits for a V6 engine: left fuel injectors #2, #4, #6 (through connector C1010, wires 706 BL/W, 708 R/Y, 710 W/BK to PCM pins 24-26) and right fuel injectors #1, #3, #5 (through connector C1011, wires 705 R/LG, 707 BR, 709 to PCM pins 27, 28, 12). Injector power comes from connector C149 (page 25-1) via circuit 701 W/R and splice S191. The knock sensor (KS) circuit with its shield is shown via connector C138 and circuit 761 W to PCM pin 7 (C247), with a note that it signals the PCM to retard timing to control engine knock. PCM ground circuits (60, 61, 63, 64 BK and 65 BK/R, 65 BK/BL) route through splices S125/S220 (auto/manual), S126 and S211 to grounds G105 and G106 via joint connectors C106. A branch to headlamps (page 85-1) and daytime running lamps (pages 97-1, 97-2) uses circuit 261 W through splices S277/S276 to C248 pin 15. Callouts explain injector pulse operation and PCM function.
