Holy Mackeral!
That is some fantastic, detailed, and helpful information!
Thanks a million. I think what threw me the most about this situation, was
not only that the cable seemed strange in that it was a shielded type... but
also the really LAME way that it was connected to the oxygen sensor cable.
The female connector is present on the ECU to O2 sensor (harness) wire...
but it appears that the O2 sensor wire was just cut (ie, someone saw that
BOTH connectors were female, and freaked out and cut the wire, stripped it,
and wrapped it around the female connector... not good) and the shielding
was also just flapping in the breeze.
Come to think of it, the guy who did this lame procedure must have been
me... as I now remember doing this about 6-7 years ago. Hmmmmm... good that
humans can learn.
I'll have to locate a "double-male" type connector when I replace it this
time.
Thanks again!
