Steering wheel issues

This should accurately simulate the appropriate voltages in the wheel. I still only get feedback when turning the wheel to the left. However, I am now getting feedback from the gas pedal. When no pedals are depressed, I get 0. I can ease the gas pedal up over 200, and pressing the brake brings it back down to 0. Pressing the brake by itself does nothing. This seems to be a mirror of what's going on in the wheel. I will be making an adapter to connect pins 5, 8, 9, and 15 appropriately, but this should help me troubleshoot until then. Based on this new info, what's your hypothesis?

I need more input. I am guessing from your description of throttle-brake that they are mechanically interconnected. Pressing the brake when you have not run up the throttle would do nothing. I am more in favor of making an adapter box where the +5 from the OI gets wired over to the four supply pins and the other wires go straight through then to modify the OI porting. A small box, two 15 pin connectors and a little wire should do it. You might also add in a "Y" adapter so that you can get to two joystick inputs on the OI. I am also more inclined to open the wheel and see what's inside than most people so that would be where I would go next.
