There was intermittent misfire in cylinder 8 and a low voltage circuit with OEM injectors that have run 20km, Ficm is fine, checked my 6 year old Motorcraft wiring harness and some wires were missing the Insulation. but it literally fell apart and was only 6 years old needed a quick replacement and this was the one next day and seems well assembled, initial thought looks better than OEM but made in China only time will tell.
