18 Here’s the AutoLoc wiring diagram for the proper switch-to-motor relationship. The Electric Life power windows should be switched 12-volt power from the ignition switch with a 10-amp fuse or circuit breaker. The AutoLoc Window Crank Switch is a billet block with two micro switches operated by a cam. All they do is reverse polarity for up or down operation. You can use a relay to activate the window but it isn’t necessary.
