A jumper from signal to ground is not trivial. The +5 pin is in the way. If you try to put a standard jumper on the ground pin, you'll short the DS power supply.
Using a servo PWM connector to bring out the signal, power, and ground connections to a SPDT switch is probably the simplest reliable way to control the DS digital inputs.
