It Looks to me like Rule R51 prohibits this sort of thing. There may be a loophole however. I believe that all the jumper does is pull a pin either high or low. there is no rule that i can see that prevents you from directly connecting this pin to a digital output. I wouldn't consider this a "custom circuit". This may be a loophole but i feel it does not go against the spirit of any rules. You are not providing a PWM outpur, not directly controlling movement and not posing a safety rist. BTW I believe the signal pin is the middle one.

This method (direct connection to the controller) was addressed last year in Q and A on the first site, and as I recall was not allowed, The relay method would seem logical even if you have to drive it with a spike. I would suggest spell out exactly how, including a wiring example and submit it to the Q and A process.
