hmm, guess i never thought about the 5V line. good point, thanks.
really, what i wanted was the 12V for heavy computing applications, and the 7V for idle. i wonder if i can somehow just have the 12V run for both switch positions and add a resistor inline to reduce the voltage to 7. i'll have to take the controller out to look at it more carefully. however, that means the computer is offline as well. hmm. i suppose we'll see if i have some time to work it out this week.
