What i found about this device is that its working by disabling ignition signal.Its adjustable by 500rpm increments.I am not sure but it might be a problem to connect it,because on 16vt engine you have 2 ignition signals because you have double coils.The device has only one channel.
You have red wire which is +12v,black -12v,yellow is RPM signal and green is ignition signal.If you have 16vt manual you will be capable to find all info you need.
You need to know if you install it that instead of a cat you should install straight exhaust pipe because cat can be easily damaged with this item.
Hope i helped at least little bit.
