2000 Land Rover Discovery 2 iat sensor

Unfortunately land rover does not include this information in their wire diagrams but what I can tell you is that the red wire is a 5 volt, the red and black wire is 8 volts, the brown and pink wire is a battery supply, the black and blue wire is a signal wire and the green and slate wire is a signal wire. Land rover only shows 2 boxes with wires going to each but does not show what they are for. The way to check this is to use a scanner and look at the live data.
