Finding the Right Fuse

The first step is to find the right fuse. But before that, you need to decide when you want the lights to come on. Do you want them to turn on with the headlights or when you start the car? This will depend on the type of LEDs you're installing.

Option 1: Lights with Headlights

If you want the lights to come on with the headlights, you'll need to locate the fuse that controls the interior lights of your car. Look for a fuse labeled as gauges, interior lamps, dash, or lights.

Option 2: Lights with Car On

Alternatively, if you want the lights to come on when the car is on, choose the fuse that controls your radio or ignition. This means that when these components are turned on, the lights will be on as well. This option may be easier than connecting the LEDs to the headlights.

Whichever option you choose, you'll need to splice into the wire connected to the specific fuse. Make sure your key is in the on position and use a multi-meter to identify the hot side of the fuse. The side without voltage, also known as the "dead" side, is the side you'll be splicing into for added fire protection.

Running New Wiring

If you want to avoid complications with your car's performance, you can also run new wiring for your LED lights. This may require more effort but can be a cleaner solution in the long run.

To do this, find a suitable ground spot. Look for a bare metal bolt without any paint or rust, as it allows electromagnetic waves to travel through uninterrupted and close the circuit. The area under the car's dash or the firewall are great places to find a solid ground spot. Remember to secure the bolt properly after completing the installation.

Consider adding an inline fuse for added safety. Connect the inline fuse close to the connection at the fuse box. Now, you can connect the positive wire of your LEDs to the positive side of the fuse and the negative wire to the negative side. Test the lights to ensure they're working correctly and mount them securely.

Finally, tidy up the wiring by using zip ties to secure any loose wires and tuck them away neatly. Following these simple steps will allow you to connect your LED lights to the fuse box of your car without any hassle.
