If, in fact, your OD is wired like that you might want to consult a wiring diagram. The grounding points in the solenoid are passed through the kickdown switch and connected to the coil. This is a ground to momentarily kill the ignition so the OD can drop out. Power for the relay is from the battery and the voltage to activate the relay is from the ignition switch.
