Check your glowplugs first if you have a P0677 or P0672 code like me... also a piece of rolled plastic instead of the guard tool that Ford wants to sell you, at a premium to do the job is all you need, coulpled with a "magnetic" 10mm socket...

I replaced the harness' on both sides, no dice...
replaced the glow plug module, no dice...
replaced the #7 glow plug, 0677 went away
replaced the #2 glow plug, 0672 went away

soooooo... don't always believe it's the harness, the plugs do go bad, don't say I didn't tell you so...:fustrate:
