What wire powers the fuel injectors on the 5.0L Ford?

Circuit 361, a Red wire that carries 12V when the relay is energized. It comes from S122 (page 24-1), passes through connector C101, and splits at splices S151 and S149 to feed all eight injectors.

What are the injector connector numbers and PCM control wire colors?

Injector #1 uses C190 with wire 555 T, #2 C191 556 W, #3 C192 557 BR/Y, #4 C193 558 BR/LB, #5 C194 559 T/BK, #6 C195 560 LG/O, #7 C196 561 T/R, and #8 C197 562 LB.

Which PCM (C185) pins connect to the fuel injectors?

The injector driver circuits enter PCM connector C185 at pins 58, 59, 39, 35, 15, 12, 13, and 14 for injectors #1 through #8 respectively.

Where do the transmission control wires from the PCM go?

Nine circuits (925 W/Y, 315 P/O, 237 O/Y, 924 BR/O, 923 O/BK, 480 P/Y, 199 LB/Y, 911 W/LG, 224 T/W) go to the E4OD transmission (pages 30-1, 30-2) or 4R70W transmission (pages 29-1, 29-2).

This document is page 24-3 of a Ford wiring diagram set covering Engine Controls for the 5.0L engine with either the E4OD or 4R70W automatic transmission. It shows the fuel injector wiring: circuit 361 (Red), which is hot at 12V when the fuel pump/EEC relay is energized, feeds all eight fuel injectors from splices S151 and S149, coming from S122 on page 24-1 and passing through connector C101. Each injector (#1 through #8) has its own connector (C190 through C197) and a dedicated PCM-controlled return wire: 555 T, 556 W, 557 BR/Y, 558 BR/LB, 559 T/BK, 560 LG/O, 561 T/R, and 562 LB, which pass through C101 to specific pins (58, 59, 39, 35, 15, 12, 13, 14) on the Powertrain Control Module connector C185. A callout notes the injectors are controlled by the PCM and mounted in the intake manifold at each intake port. The bottom of the page shows nine transmission control circuits (925 W/Y, 315 P/O, 237 O/Y, 924 BR/O, 923 O/BK, 480 P/Y, 199 LB/Y, 911 W/LG, 224 T/W) leaving the PCM to the E4OD (pages 30-1, 30-2) or 4R70W (pages 29-1, 29-2) transmission diagrams.
