OK first a question, why do you think they "suck" electricity? The only time they draw anything is when you apply the brakes, and they don't draw much amperage at all, they are just a solenoid. That being said, just follow the wires up to the wiring harness and pull the plugs. If you notice, the wires are very thin to begin with which should tell you they do not draw very much amperage. If you want to do it the fast way just cut the wires and insulate the cut end...
