I've posted a new Web page documenting the fabrication of steel replacement shift paddles for the Logitech Wingman Formula Force and replacement of the fault-prone LWFF shift switches with rugged microswitches:
I'd previously announced a page with detailed instructions for modifying a Logitech Wingman Formula Force wiring harness to allow interchanging the stock pedals with unmodified Act Labs Performance Pedals. This permits use of the Act Labs pedals with sims that do not support multiple game controllers in Windows, allows plug-in restoration of the original Logitech pedals, and removes the redundant set of pedals from the system by relocating force-feedback DC power to a custom-made breakout box. The information contained within the page may also prove helpful to someone attempting a similar modification with other wheel/pedal combinations.
