installation is very easy.. All you need is a tiny flat-tip screwdriver and a hex key wrench.
Use the small flat tip driver to pries open the little bolt cover on the accelerator pedal assembly. Once that's removed, loosen the hex bolt and remove it. The accelerator pedal assembly then needs to be lifted up and out (careful with the DBW cable). After that, you just unplug the DBW cable and put this device in between the two cables.
