I'm a little confused. Why are you attempting to disconnect the harness end if you only need to cut
the wiring (leaving the plug end alone) and SPLICE in the new sensor into the existing wiring?
I could understand your situation IF you were replacing an entirely new sensor ASSEMBLY with the plug end already on it.
Which engine? 2.0 four banger?
