Hey, I got this 97 Range Rover HSE, I have been replacing sensors left and right. I just put in some height sensors, and a bonnet sensor, a Door latch (Sensor) for the drivers side door. It sat for about 2 months with a dead battery and all the windows and such need to be reset. I need to sell it but it won't come out of park now. I know there is a switch somewhere to bypass the lock, but I hear its a pain in the ***. I was told to replace the break pedal sensor, but I went to go buy 1 and the guys at the dealership told me there is only 1 sensor, where my mechanic told me there is 2. The break lights work when i press the break.

So,
1. are there 2 parts to this sensor?
2. What else could this be?

Also is there a diagram/pdf file that could show me where the saftey override switch is?
