When it comes to wiring a hazard switch, there are many variations available. In this article, we will take a look at the 8 pin hazard switch wiring diagram, its functionality, and how to install it. We will also provide some frequently asked questions to help you understand this topic better.
What is a Hazard Switch?
A hazard switch is a car part that is used to indicate when a vehicle is in danger or needs caution. It typically flashes the turn signals on both the left and right sides of the vehicle simultaneously, letting other drivers know that the driver is experiencing some type of problem on the road.
A hazard switch is usually located on the dashboard or center console of a car. It can either be an independent switch or integrated into the turn signal switch. Regardless of its location, the hazard switch is an important component of a car’s safety system.
Function of an 8 Pin Hazard Switch
The 8 pin hazard switch is one of the most commonly used hazard switches in modern cars. It is designed to work with both mechanical and electronic flashers, and it has eight pins on its back that connect to the car’s electrical system.
The 8 pin hazard switch has a few different functions. Firstly, it records when the hazard lights should be activated, and when they should be turned off. This is done with the help of a timer relay, which is integrated into the switch.
Secondly, the 8 pin hazard switch also allows the driver to activate both the left and right turn signals simultaneously. This is done by turning on the hazard light switch, which in turn causes both turn signals to come on at the same time.
Wiring an 8 Pin Hazard Switch
Before you start wiring an 8 pin hazard switch, you should gather all the necessary tools and equipment. This includes a wiring diagram, wire strippers, crimping pliers, electrical tape, and a test light.
Step 1: Disconnect the Battery
Before you begin to wire the hazard switch, it is essential to disconnect the battery to ensure that no electrical current is flowing during the installation.
Step 2: Identify the Wiring Connections
The 8 pin hazard switch has eight pins on its back. Each of these pins connects to a specific wire in your car’s electrical system. You will need to identify these connections before you start wiring.
The wiring connections are as follows:
| Pin Number | Wire Color | Connection |
|---|---|---|
| 1 | Green | The battery positive terminal |
| 2 | Orange | The left turn signal wire |
| 3 | Blue | The right turn signal wire |
| 4 | White | The hazard lights power wire |
| 5 | – | Not used |
| 6 | – | Not used |
| 7 | – | Not used |
| 8 | Brown | The ground wire |
Step 3: Connect the Wires
Once you have identified the wiring connections, you can start connecting the wires. Follow the wiring diagram carefully to ensure that you connect the wires correctly.
Connect the green wire to the positive terminal of the battery, the orange wire to the left turn signal wire, the blue wire to the right turn signal wire, the white wire to the hazard lights power wire, and the brown wire to the ground wire.
Step 4: Test the Hazard Switch
Once you have completed the wiring, it is time to test the hazard switch. Reconnect the battery, turn on the ignition, and test the switch by activating the hazard lights. If the lights flash on both sides of the car, the hazard switch is functioning correctly.
