## Wiring Diagram 2 Pin Flasher Unit

A flasher unit is a small electrical device that is used to flash the turn signals on a vehicle. It is typically a cylindrical object with two terminals, one for power and one for ground. The flasher unit contains a small electronic circuit that causes the turn signals to flash at a specific rate. The wiring diagram for a 2-pin flasher unit is relatively simple. The power wire from the fuse box is connected to one terminal of the flasher unit, and the ground wire is connected to the other terminal. The flasher unit is then connected to the turn signal switch. When the turn signal switch is turned on, power is supplied to the flasher unit. The electronic circuit in the flasher unit then causes the turn signals to flash at a specific rate. The rate at which the turn signals flash is determined by the resistance of the flasher unit. The following is a wiring diagram for a 2-pin flasher unit: ``` +----------+ | Fuse Box | +----------+ | | | | | | | | 1 | 2 | 3 | | | | +----------+ | Flasher Unit | +----------+ | | | | | | | | 4 | 5 | 6 | | | | +----------+ | Turn Signal Switch | +----------+ ``` In this diagram, the following connections are made: * Power wire from the fuse box (terminal 1) to terminal 4 of the flasher unit * Ground wire from the fuse box (terminal 2) to terminal 5 of the flasher unit * Turn signal switch (terminal 3) to terminal 6 of the flasher unit This wiring diagram will work for most vehicles, but it is always best to consult your vehicle's owner's manual to verify the correct wiring. ## How to Install a 2-Pin Flasher Unit Installing a 2-pin flasher unit is a relatively simple task that can be completed in a few minutes. The following steps will show you how to install a 2-pin flasher unit: 1.

### Locate the old flasher unit.

The old flasher unit is typically located under the dashboard, near the fuse box. 2.

### Disconnect the power and ground wires from the old flasher unit.

The power wire is typically a red wire, and the ground wire is typically a black wire. 3.

### Install the new flasher unit.

The new flasher unit should be installed in the same location as the old flasher unit. 4.

### Connect the power and ground wires to the new flasher unit.

The power wire should be connected to terminal 4 of the flasher unit, and the ground wire should be connected to terminal 5 of the flasher unit. 5.

### Turn on the ignition switch.

The turn signals should now flash at a normal rate. If the turn signals do not flash at a normal rate, you may need to adjust the resistance of the flasher unit. The resistance of the flasher unit can be adjusted by turning the adjustment screw on the side of the flasher unit. Turning the screw clockwise will increase the resistance, and turning the screw counterclockwise will decrease the resistance. ## Conclusion A 2-pin flasher unit is a simple device that is used to flash the turn signals on a vehicle. It is relatively easy to install and can be replaced in a few minutes. If you are having trouble with your turn signals, it is possible that the flasher unit is the problem. By following the steps in this article, you can easily install a new flasher unit and get your turn signals working properly again.
