Step 1: Install the foglights.

The first step is to install the foglights on your vehicle. This will vary depending on the make and model of your vehicle, so you'll need to consult your owner's manual for specific instructions.

Once the foglights are installed, you'll need to connect them to the wiring harness. The wiring harness will have two wires: a positive wire and a negative wire. The positive wire should be connected to the power source, and the negative wire should be connected to ground.

Step 2: Install the relay.

The next step is to install the relay. The relay will be located in the engine bay. It will have four terminals: 85, 86, 30, and 87. The 85 and 86 terminals will be connected to the battery, the 30 terminal will be connected to the power source for the foglights, and the 87 terminal will be connected to the foglights.

To connect the relay, you'll need to strip the ends of the wires and solder them to the terminals. Once the wires are connected, you'll need to cover them with heat shrink tubing to protect them from the elements.

Step 3: Connect the wiring harness to the relay.

The final step is to connect the wiring harness to the relay. The wiring harness will have two wires: a positive wire and a negative wire. The positive wire will be connected to the 87 terminal on the relay, and the negative wire will be connected to the 86 terminal on the relay.

Once the wiring is connected, you can test the foglights to make sure they're working properly.

Troubleshooting:

If the foglights are not working, there are a few things you can check. First, check to make sure that the relay is installed correctly. Second, check to make sure that the wiring is connected correctly. Third, check to make sure that the foglights are turned on.

If you're still having trouble, you can consult your owner's manual or a qualified mechanic.

Wiring in foglights is a relatively simple task, but it's important to make sure that you do it correctly. By following this guide, you can safely and easily add foglights to your vehicle.
