where is the knock sensor located on my 05 LR3 HSE

The difficult part, I've found, is the removal of the electrical connectors because they have small metal brackets in them that mount to the vehicle (usually with rusty hardware).

+Rich Yaeger any tips on this? I spent 2 hours last night trying to get them off the bracket. I got them to wiggle in an up and down movement. But can't find any tab to release them.

just curious - a LR repair place wanted to charge me $700 to do this? I bought the parts for 40$ online and did it in a snap (no pun intended). I would much rather pay a local LR repair man to do this! but $700???
