Knock sensor wiring?


Recommended Posts

I was under the '88, 4.0L, 5-speed MJ today and noticed a bare stranded wire that goes nowhere in the knock sensor harness. Does this belong some where? I see two wires that go to the knock sensor connector that are intact. On my other two MJs, the wires that lead to the knock sensor have a sheath over them and the wires are not visible. The MJ does develop a "rattle" above 2500 RPM in any gear, even neutral. Is this loose wire the cause? Any help is appreciated.

I can't really tell what wires you are talking about from your pic, but there are three sets of wires in that subharness. One set for the knock sensor, one set for the O2, and one set for the coolant sensor. All of yours hooked up?
