   been workin on the car the last couple of days and when i took my induction kit off to change the temperature sensor there was a brown sensor under the temp sensor connected to nothin?????????? there was another brown one with loom goin under throttle body and another blue one which i think is another coolant sensor for the dash light. anyone got any ideas what this brown one is and what it does? can someone check their motor?

   you think they would just bung it, thanks fellas, just checked haynes manuel and looked at wiring diagram and i think it is an air con sensor. as danboy says...

   As above.
   
   I replaced my temp sensor yesterday and thought 'blimey whats this?' but apparently it's to do with air con for continental models.

   Reverse gear sensor? You got reverse lights working? That sensor is usually a brown top.
