What wire colors go to the left bank fuel injectors (#2, #4, #6)?

The left fuel injectors at connector C1010 use circuits 706 BL/W, 708 R/Y, and 710 W/BK, with power supplied on 701 W/R.

What wire colors go to the right bank fuel injectors (#1, #3, #5)?

The right fuel injectors at connector C1011 use circuits 705 R/LG, 707 BR, and 709 W, also fed by 701 W/R.

How does the fuel injector operate according to this diagram?

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

Where does the knock sensor connect?

The knock sensor (KS) connects through connector C133 on circuit 65 BK/R, with a knock sensor shield on 761 W from C247 and a 65 BK ground path. It sends a signal to the PCM to change timing to control engine knock.

Where are the PCM ground circuits shown?

Grounds include 60 BK through S125 (auto) or S220 (manual), 63 BK and 64 BK through S126 to ground G105, and 65 BK/R and 65 BK/BL through S211 to joint connector C106 and ground G106. Ground details are on pages 10-9, 10-10, and 10-11.

This is a page from a Ford factory-style wiring diagram covering the fuel injector and Powertrain Control Module (PCM) circuits, apparently for a V6 engine (six injectors). Power from connector C149 (page 25-1) feeds circuit 701 W/R through splice S191 to two injector banks: the left fuel injectors #2, #4, #6 at connector C1010, and the right fuel injectors #1, #3, #5 at connector C1011. Injector control wires run to the PCM: 706 BL/W, 708 R/Y, 710 W/BK (left bank) and 705 R/LG, 707 BR, 709 W (right bank). The diagram also shows the knock sensor (KS) circuit with shield (761 W, 65 BK, 65 BK/R at C133), PCM grounds via 60 BK through splices S125 (auto) or S220 (manual), 63 BK and 64 BK through splice S126, and 65 BK/R and 65 BK/BL through splice S211, terminating at grounds G105 and G106 via joint connectors C106 (see grounds pages 10-9 through 10-11). A daytime running lamps/headlamps branch (261 W through splices S277 and S278, pages 85-1, 97-1, 97-2) connects to the PCM at C248. Explanatory callouts describe injector pulse-width operation and the knock sensor and PCM functions.
