Well... There's your problem. No idea what happened to the rest of the end of it, and I was sure I bought a not-exactly-cheap part yet it's entirely unbranded. Huh. Well, new one is in, haven't had a chance to run it yet as I've been dragged away, but will tonight.
Also, while looking around and checking everything, I came across this single pin round blue wired connector just by the airbox, extending out of the same loom as the Oxygen sensor. Does anyone have any idea what this is for? If anyone recalls our XJ had a replacement motor put in somewhere in the late 90's and we suspect it may be from a Grand Cherokee given certain parts on it. My only concern is if there was a temp sensor somewhere that the stock XJ 4.0 uses that the GC one didn't have, and they just taped it up during the swap. The tape wrap on it was NOT factory, that much is certain.
I checked XJ and GC wiring diagrams and I swear I can't locate it ANYWHERE
