Thanks Don. Yes, as I hinted, a "new" one may be in the works.

The issue with the shielded wiring is not at the wires between plug and
sensor. i.e. the knock sensor part itself. Its at the wires in the harness
after that plug. In terms of the knock sensor, no doubt the device is
pretty simple but as with the O2 sensor, the amount of volts it imparts is
in the millivolt range. So, any advantage I can get (less resistance) to
carry those millivolts, is welcome.

The junkyard here (only one) is limited in its' supply and asks WAY too
much for parts. More time on craigslist coming up...   It may be that I
switch to the OBD2 platform in the process. Get as new a model year ABA
harness as i can

Neil.
