Knock Sensors Is there an "updated" version of knock sensors from GM? I am going replace my knock sensors and have seen several different posts with alot of different part numbers. My car is a 98 Trans Am.....I also need to replace the knock sensor wire harness....is there just one harness for both sensors or do you have to order two separate harnesses?

Ok......after talking to some techs at the GM garage and searching numbers on dealer sites....I came up with the following....
Knock Sensors.....10456222 replaced by 10456603 replaced by 12589867 (most current)
Harness.......12601822 to go with the 12589867 sensors.
The original sensor harness is no longer stocked according to my local dealership.
