PaulRB:
For the switches, as you already figured out, you just need a known resistor for each arduino analog pin (between 5V and the pin). Try 10K, 4K7, 2K2, 1K... and see what analogRead() gives for each switch.
I attached a breadboard view of how I am planning to connect the SW1 and SWG pins along with the known 10K resistor. Did I connect everything correctly? For some reason, something seems off with my breadboard sketch... As if there is an incomplete circuit...
If I am not mistaken, SW1 is for the first Steering Pad Switch. And SWG is Ground for both of the Steering Pad Switches.
