Follow up... rather than buying a new plug (mine was fine) I just replaced the wiring and soldered it into the loom. You can do this using part number 000979034EA (it comes as one length with a connector at each end so you cut the cable in half to end up with two cables).
Photos attached... the yellow cables are the new ones mid-installation. I also added a small connector / tie wrap combo to hold the offending cable / pipes apart so that it doesn't happen again.
