4 pin relay schematic to wire in foglights

As a car enthusiast, you may be familiar with the term “fog lights” and what they do. But did you know that a 4-pin relay schematic can be used to wire these lights into your vehicle? This article will discuss the basics of how to wire in fog lights using a 4-pin relay schematic and provide tips on troubleshooting any issues.

First, let's take a look at what a 4-pin relay schematic looks like. A 4-pin relay schematic typically has four terminals labeled as 30, 85, 86, and 87. Each terminal is connected to a wire in the relay. The terminal labeled 30 is generally connected to either the battery or a fused power source. The 85 and 86 terminals are connected to the high voltage side of the fog lights, while the 87 terminal is connected to the low voltage side.

When setting up the 4-pin relay schematic, it's important to make sure that all of the connections are secure and properly insulated. Once the connections have been made, the next step is to test the lights. Testing the lights can be done by turning on the headlights and then switching the fog lights on and off. If the lights turn on and off correctly, then the wiring job was a success.

The 4-pin relay schematic is a great way to wire in fog lights and add a bit of flair to your vehicle. With some basic knowledge and a little patience, you can easily install fog lights and enjoy the improved visibility they offer. Just be sure to check all of the connections, use proper insulation, and test the lights before driving.
