For drivers using a Simucube 2, we build a harness that connects the pedals to the wheel base directly. There are 2 benefits. First is that you use 1 USB port on your PC for pedals, wheelbase and handbrake (if you have a Sim Coaches Pro Handbrake as well.) Second benefit is that the Simucube has a 16 bit controller inside making it read at a higher resolution.
