Fog Light Wire Harness Shopping Tips
Your car's fog lights help you see through dense fog during inclement weather. These lights that are located beneath the headlights have separate wire connections leading to the switch at the driver's firewall panel. You have to ensure that the wires are properly connected so that you do not find yourself groping for the road when safe passage through fog is needed. Fog light wire harnesses are actually small stuff compared with other crucial car parts, but these perform a very specific function that you should not ignore.
How and what to look for?
The easiest way to shop for fog light wire harnesses is to do an online search. There are many auto parts stores that stock up on replacement car components like wire harnesses. Look for sites that give you a wide shopping horizon when it comes to brand and price options. You can even save if you look through discounted parts first before checking out the bestsellers. Do not forget to compare prices of products in a site; comparing products and pricing between sites is also a good way to shop. Go for OEM fog light wire harnesses because these are price-competitive, have a universal fit, and are as reliable as the branded ones.
What to do once the unit is found?
When you think you have the right product, check it if it has complete parts. A fog light wiring harness must include a wire harness, a switch, and a relay. Choose a pre-terminated wire harness if you do not want hassle in connecting the wires to the other components in the set. Also, set descriptions indicate the number of fog lights that the wire harnesses can accommodate. If you are replacing two fog lights, make sure that you buy one wire harness for each. You should also note if you need to have wire brackets and fasteners, because these harnesses can get dangly once installed behind the bumper.
Simple Fog Light Wire Harness Installation
It is difficult to surpass an inclement weather if you do not have fog lights installed on your car. These are a set of special lights to help you see through low visibility, and they have wire connections that can be tricky to install for do-it-yourselfers. So, if you do not have the knack for wires, say, you always have any type of wire tangled, here is the guide you need to help you install your own wire harness for your fog lights.
Note: The following steps lead you through the installation of the wire harness, subharness, and relay harness.
Warning: Make sure the vehicle is turned off and the negative battery terminal is removed.
Difficulty level: Moderate
- New fog light wire harness (ones appropriate for the model of your car; includes a set of wire harness, subharness, relay harness, and relay bracket)
- Wire ties with holder
Routing the wire harness
Step 1: Route the wire harness to connect the two fog lights. First, plug the 2-pin connector of the wire harness into the left fog light. Then, secure the harness with the 4-pin connector clip.
Step 2: Find the green tape on the harness. Install the wire tie with holder around the harness at the green tape. Attach the wire to the left fog light cover.
Step 3: Connect the wire harness to the right fog light. First, route the 2-pin connector of the harness to the right side of the front bumper. Then, plug the 2-pin connector into the right fog light. Secure the routed harness with the wire tie, then attach the clip to the right fog light.
Step 4: Secure the loose parts of the wire harness to the front grille using wire ties. Make sure that no part of the harness dangles away from the grille.
Routing the subharness
Step 5: Connect the subharness 1-pin connector to the vehicle's 1-pin connector located below the driver's headlight.
Step 6: Remove the vehicle ground bolt. Install the subharness ground terminal, then secure it to the vehicle's ground terminal with the bolt.
Step 7: Put the wire tie with clip to the subharness at the green tape. Insert this clipped wire tire into the hold in the vehicle frame. Use a wire tie to secure the 1-pin connectors to the vehicle harness. Plug in the subharness 4-pin connector.
Routing the relay harness
Step 8: Make sure that the relay harness is installed into the relay block. Plug the 8-pin connector of the relay harness into the 8-pin connector on the fuse box. Connect the 1-pin connector of the relay harness to the 1-pin connector on the vehicle.
Step 9: Secure a relay bracket to the vehicle panel using a hood opener bolt. Install the connector clip onto the relay block of the relay harness. Secure the relay block connector clip to the relay bracket, then secure the relay harness to the vehicle harness with wire ties.
