How to Wire Up a Start Capacitor | Hunker Push the wire terminal on the start capacitor's second wire onto the run capacitor's common terminal, often labeled "C," "COM." The wire connected to the motor's run terminal, marked as "R" on the motor's wiring chart, and the wire going to the hot terminal on the load side of the contactor also connects to this run capacitor terminal. Electric Motor Starting Capacitor Wiring & Installation More complex case: a motor that also can have its run direction swapped between clockwise and counterclockwise - adding 2 to 4 wires.
