Speedo Correction Kit

SKU: BA5250


The TD5, 2.4 and 2.2 TDci Defenders have a green 3 wire transducer fitted behind the handbrake back-plate to the speedo drive gear. This generates a pulse which is sent to the dash clocks to show the vehicle speed.

If you fit the different size tyres or different ratio ring and pinions in the diffs then the speed displayed may well be inaccurate.

This small device is very easy to install and program. It allows you to adjust the output pulse both up and down, which means the dash clocks see the correct pulse and this shows the correct speed.

Remove the centre seat cover and look for the small 3 wire loom coming from the speedo driver transducer, this loom joins a fat loom at the top of the transfer case.

We would suggest fitting the controller under the right hand seat and running the 4 wire loom alongside the fat loom to the top of the transfer case then join the 4 wires to the 4 wires before they enter the big loom as follows:

Join the |Red wire to the White/Green wire.

Join the Black wire to the Black wire

Cut the Black/Red wire and join the transducer side to the White wire.

Join the other side of the Black/Red wire to the Green wire, note the colours of then genuine 3 wires above are from our 2007 2.4 TDCi Defender, if yours vary, there are 3 symbols marked inside the plug on the green transducer:

+= White/Green

-= Black 

A= Black/Red
