Does anybody have a good way to unplug/remove the harness without fukkin it up. These damn brittle plastic piece of shyts. Does the removal tool actually work?
In my opinion, no these just suck. I have had to break them into pieces just to get them out of the head. Easiest way is with the injectors out, pop them out with a pry bar or small lady foot. I always replace harnesses and all glow plugs on a side if one goes bad.
I leave them in the rocker boxes, and when I pull those, I push them out from the backside with a socket, never break them. That is, of course, if you're digging in that far. I have a bad glow plug and have been sitting on it for a long time waiting to pull the heads for studs, knowing full well I'd likely break that stupid harness doing it before.
