Defender - Td5 and 2007 Onwards
Behind the handbrake back plate , on later defenders, is a green wire transducer which generates a pulse. This is then sent to the speedometer to show your vehicle's speed.
Fitting different sized tyres or a non-standard ratio ring and pinion in the diffs could well mean the speed displayed is then inaccurate, so that's where the Speedo healer comes in
Fitting and programming this box is easy, and once installed allows you to adjust the output pulse, both up and down, meaning you can set the correct speed at which you are travelling.
The instructions included detail how easy it is to program the box using a sat nav system.
