Locate the engine. Club Car engines are housed under the passenger seat and can be accessed by simply pulling up on the seat and putting the seat into the foot well. The engine will be sunk several inches into the opening to protect it from accidental contact.
Locate the throttle. There should be a cable leading to it. That will lead to what you are ultimately trying to find--the governor. If you have trouble finding the cable, use the flashlight to guide you from the gas pedal to the engine.
Find the governor. The governor is located just under the throttle cable and has a hole in it.
Neutralize the governor. As the throttle asks the engine for more and more power, the governor spins faster and faster into the engine to regulate the power, thus controlling the speed. You want to neutralize that process. Stick a tee in the governor hole so that when it starts to spin, it can't go into the engine.
