Components of an EZGO Golf Cart Wiring System
Before diving into the wiring diagram itself, it’s essential to familiarize yourself with the key components involved in the electrical system of an EZGO golf cart.
Battery Pack
The power source for the golf cart, typically composed of 6-8 deep-cycle batteries connected in series to provide the required voltage, usually 36V or 48V.
Key Switch
The main power switch that controls the connection between batteries and the rest of the electrical system.
Throttle (Accelerator Pedal)
Sends signals to the controller based on pedal position, regulating speed.
Controller
The electronic device that manages power flow between batteries and the motor based on throttle input.
Motor
The electric motor that drives the wheels, either AC or DC depending on the model.
Solenoid
Acts as a relay, engaging the circuit from the battery to the controller and motor when the accelerator is pressed.
Fuses and Circuit Breakers
Protect the system from overloads or short circuits.
Lighting System
Includes headlights, taillights, and indicators connected via specific wiring paths.
Additional Accessories
Speakers, USB ports, chargers, or lift kits that may require additional wiring connections.

Common EZGO Golf Cart Wiring Diagram Types
Depending on the model and year, EZGO golf carts have different wiring configurations. The most common types include:
Pre-MCI (Pre-2008) Wiring Diagrams
Older models with simpler wiring schemes, typically 36V systems with basic controllers.
TXT Series (2008 and later)
Features more advanced controllers and wiring harnesses, often with 48V systems.
RXV Series (2013 and later)
Modern models with AC motors, CAN-bus systems, and more complex wiring diagrams.
Electric vs. Gas Models
While electric models rely heavily on wiring diagrams, gas models have minimal electrical wiring but still require understanding for accessories and lighting.
