I'm trying to take the remaining glow plug cap off, but when I try to undo the nut, the whole wire comes around with it, putting the wire at a sharp angle. This can't be good for it.

I've loosened the nut up as much as I can, but can't get the wire, even by force where I can get my hand in there, or with pliers, to remain still while I undo the nut. They're stuck together. I've put a bit of wd-40 on it to try to help loosen it up (don't have any liquid wrench around), but it still spins with the nut.

Any suggestions? I don't want to mess up the glow plug wiring harness.

Thanks,
