Which PCM pin does the misfire sensor signal wire (917 DG/LG) connect to?

Circuit 917 DG/LG runs through connector C1027 to pin 59 of the Powertrain Control Module (PCM).

What wire color and circuit number is the misfire sensor ground/shield wire?

Circuit 651, black/yellow (BK/Y), which passes through the misfire sensor shield, joins at splice S127, and goes to PCM pin 6 via connector C110M.

Which connectors are in the misfire sensor circuit?

C114 (at the sensor), C101F/C101M, C110M, and C1027 at the PCM. Splice S127 is also shown.

Are any wires in this diagram marked as not used?

Yes. Circuit 136 DB/Y to PCM pin 84 and one 651 BK/Y branch are both labeled (NOT USED).

This document is page 96 of a wiring diagram set, section 25-6 'Engine Controls, 5.8L Under 8500 GVW.' It shows the misfire sensor circuit for the 5.8L engine. The misfire sensor, described in a callout as being 'used to identify change in crankshaft rotational speed to indicate cylinder misfire,' connects through connector C114. Circuit 917 (dark green/light green, DG/LG) runs from the sensor through connectors C101F/C101M and C1027 to pin 59 of the Powertrain Control Module (PCM, solid state). Circuit 651 (black/yellow, BK/Y) provides the sensor ground/shield path, passing through the misfire sensor shield (shown as a dashed oval) and joining at splice S127 before reaching PCM pin 6 via connector C110M. Circuit 136 (dark blue/yellow, DB/Y) to PCM pin 84 is marked NOT USED, as is one 651 BK/Y branch. An arrow indicates the circuit also connects to the ignition system, referenced on page 21-1. A reader can learn the wire colors, circuit numbers, connector identifiers, splice location, and PCM pin assignments for the misfire sensor on this application.
