Knock sensor

Hello S type owners... I read the post on replacing the knock sensor on the 4.0 Jag S type, but the 2003 does not figure the same. My code says bank 1/so Bank A/ passerger side. I cannot find a knock sensor anywhere on this side. On the drivers side attached to the top rail is the connector for a knock sensor. I have the replacement part and the connectors are the same and the 2 wire cover is green and black ( the same). It connects there and travels under the air intake to who knows where... the wire length is about 20" ...the connection to the engine is a round rubber 3/4" wide affair with a 3/8" hole in the middle. I cannot find anything to match this on the passenger side !

Any thoughts as to what is next? john...read that both knock sensors are under the intake plennum..will remove it and go from there...

Wordman, jagv8 will likely visit this post and direct you to a schematic of the 4.0 motor with sensors. He's pretty darn good with schematics (tech info.). Good luck, all shall be well.
