I have a 2008 F-150 4.6L 2 wheel drive that someone unhooked the 3 wire harnesses going into the PCM. Question is which wire harness plugs into the 3 slots on the PCM,? On the PCM one slot is smaller them the other two so I know the slot for that wire harness. The other 2 connectors are the same size, I have a wire harness coming from behind the engine and one coming from the battery compartment.

Jimboy, Thank you it worked.

 

I have a 2004 Ford F150 5.4 L it hasn’t started in about two months. We’ve replaced absolutely everything from the alternator to the starter to the fuel pump fuel pump driver module relays starter. Spark plugs, coils and and it’s turning over, but it will not crank we found this plug off of the engine wire ring harness, and cannot figure out where it plugs into. I took as many pictures as I can please please help.
