Can anyone help me identify the pink/black wire that was shorting on the left valve cover of my 2003 7.3L F250? The wire is in the harness from the PCM/IDM that attaches to the 42-pin connector. I have not found complete circuit diagrams or pin-out schematics in the Ford workshop manual, or the power control and emissions diagnostics manual.
Does Ford publish full wiring diagrams for the engine control systems? Is the International diagnostic manual for this engine (EGES-125-1) a better source for this information?
The short caused an intermittent misfire, especially in humid conditions, although the injector buzz test was normal. I repaired the damaged wire by soldiering in a short length of new wire and covered it with heat shrink tubing. The other scuffed wires (no copper showing) were wrapped with vinyl tape then the whole bundle was wrapped with a self adhesive silicone tape to pad the harness and seal out moisture. Finished with red vinyl tape to match the factory stripes. Lol. So far, so good.
