I'm getting the 'bonnet open' message and have read the posts about replacing the sensor. I've tried unplugging and cleaning it and that worked for a week but now it is back so I want to replace the sensor. What I don't know is how the replacement works, because it seems from looking at it that the wire is spliced in somewhere with other wires and I don't want to damage anything. See the attached pictures, how the wire from the sensor plug leads into a larger bundle of wires which are wrapped in insulation. Any guidance from those of you who have done this before?
