10 Year Warranty
Like all previous Yellow Box versions, this is a high quality product produced
in Australia by craftsmen. We are proud of our quality control and extensive
testing during manufacture and we back this up with our 10 Year Warranty.

 

If your Yellow Box fails within 10 years of purchasing we will replace it
with a new product. You pay the postage to us, we pay the return postage.


Speedo correction
The Yellow Box unit is installed permanently in the vehicle and performs real-time
correction of the speedometer signal.

 

The Yellow Box receives electrical pulses from the vehicle speed sensor.
The high-speed microcontroller (tiny computer) inside the Yellow Box uses
our proprietary software to precisely correct the signal pulses in real time.

 

With only 4 wires the Yellow Box is a fairly simple installation. Plug-n-play harnesses
are available for many motorcycles, older 4WDs, and some sportscars, but in other
models you will need to splice the Yellow Box into the speedo sensor wiring and
provide +12volt (or +5volt) power and ground.

NOTE! The Yellow Box has been very carefully tested before it leaves
our factory and is guaranteed to be working. Installation in the vehicle
requires a certain amount of expertise so please consider using an auto
electrician if you think you may have trouble installing it.

We can only provide a small amount of tech support time per customer,
so please check your installation carefully! Many vehicle forums have
Yellow Box installation guides available.
