    wire in the knock sensor?

    if you're convinced the wiring is 100% correct:
    -replace the KS
    -chip the ECU with a program that doesn't look for knock

    I grabbed harness ends from the junk yard, and pulled out some of the pins with the color or wire I wanted. Solder each end of the wire and pop your new pin in the right slot. Presto, like it was always there.
