Does anyone know the part number of the wiring harnees that the four O2 Sensors plug into on a 99' WJ w/ calif emissions?
im getting two codes that indicate that the wiring has gone bad for the two downstream o2 sensors which i have already replaced.
before i replaced them, it was having really bad hesitation and shaking, and when i replaced them, it seemed to fix all the issues for a couple weeks, then the codes and the hesitation shaking came back, so im thinking the wiring harness may be bad as well, but i cant seem to find the part number, or even a technical name for it. it looks like the wiring harness has already been attempted to be repaired as the plastic covering is broken in places and has electrical tape underneath the protective plastic covering.
im hoping its not the two mini catalytic converters which have gone bad, which run close to $400 each.
