4 Pin Flasher Relay Wiring DiagramA flasher relay is a type of electrical switch that is used to flash the lights on a vehicle. It is typically a small, cylindrical device with four terminals. The two terminals in the center are connected to the battery, and the two terminals on the outside are connected to the lights. When the relay is activated, it sends a signal to the lights to turn on and off. The wiring diagram for a 4 pin flasher relay is relatively simple. The following diagram shows the basic wiring for a flasher relay that is used to control two lights: [Image of a 4 pin flasher relay wiring diagram] As you can see, the positive terminal of the battery is connected to terminal 3 of the relay. Terminal 1 of the relay is connected to the ground. Terminal 2 of the relay is connected to the switch that controls the lights. And terminals 4 and 5 of the relay are connected to the lights. When the switch is turned on, it completes the circuit between terminals 2 and 5 of the relay. This causes the relay to activate, which in turn sends a signal to the lights to turn on. When the switch is turned off, the circuit is broken and the lights turn off. Flasher relays are available in a variety of different sizes and styles. They can be purchased from most auto parts stores. ## How to Install a 4 Pin Flasher Relay Installing a 4 pin flasher relay is a relatively simple task.
