The Box is a stand alone USB device mainly use for RA function in GT5 & as a device hubs to connect Sequential shifter , wheel horn botton, wiper & light control stick, handbrake or other something want to connect, through this box ,no need to wire these several device directly on the steering wheel pcb any more, also can disconnect /replace the device easily.
Another function is for Reverse Gear in sequential/paddles shift mode.
Why I made this box was because, there are no key remap for G27 in GT5,and I don't want to hold a DS3 on hand or stick it on the wheel to access all in game function, other reason is, I think the Reverse button on G27 shifter keypad are too far away from wheel, make it closer to the wheel is much more better for me. And I also don't like put all button on the wheel,
so this box are 100% personalize device for my own usage~
