Light Up with the Perfect Headlight Wire Harness
It is true that everything in your automobile is perfect for what you need on the road, but this doesn't mean that you can't improve some of them. A good example is your headlight. You can enhance its output by simply replacing or upgrading its wire harness to a newer, better aftermarket product these days. This is especially true if you have 20-22 gauge wirings that can preserve the service life of your headlight but limit its output to a minimum. Whether for upgrade or simple replacement purposes, choose a wire harness considering these factors:
- 10-gauge wires. Bigger wire means more volts going to the headlights, and therefore more light. This size is sometimes custom made. But, if you will be able to find a direct-fit for your type of headlight, get a new harness with this wire size.
- 14 to 16-gauge wires. These are thicker alternative wire choices when replacing your old and output-restrictive headlight wire harness. Look for an aftermarket part within this size range to ensure better performance and service life from your headlight.
- 20 to 22-gauge wires. These sizes are common among factory wires. Though they ensure the lasting service life of your vehicle light, they can limit the part's output. If you want the original performance of your lighting equipment, get the perfect match for your old wiring harness from this range of wire size.
- OE parts. In any case, original equipment parts are the best choices whenever replacing your factory components because of the seamless fit they can offer. But, they are also a bit pricey, which is why so many enthusiasts prefer aftermarket replacements that are especially made for their vehicle make and model. If budget is not a concern for you, as well as the original performance of your old harness, this is the best pick.
- Aftermarket products. Whenever price has become a problem for you, choose a direct-fit replacement. Just make sure that it is compatible with the specifications of your vehicle to ensure that it will work and restore the performance of your lighting equipment. This should also be your choice when thinking of upgrading the performance of your headlight, as aftermarket headlight wire harnesses are engineered with better technology. They also offer better designs with more visible colors that improve the overall appearance of your wiring system.
Step-by-Step Installation of a Headlight Wire Harness
You can always upgrade the performance of your headlights without spending too much on replacements. One of the countless ways is by replacing its wire harness with a performance aftermarket harness. If you haven't noticed yet, your factory wire harness is designed to meet the service life of your lighting equipment at the expense of its performance. All you need to do is get bigger wires in to hoard larger voltages for your headlights, enjoying better output and service life. If you are up for the challenge, do the task yourself using these steps:
Difficulty level: Moderate
Things you'll need:
- New headlight wire harness
- Male/female connectors
- Cable or wire ties
- Electrical tape
- 10mm and 13mm sockets or wrenches
- Pliers or crimp tool
- Wire cutter and stripper
Wait for your engine to cool before fiddling with your old harness.
Step 1: Remove any fusible links from the old harness. Mark or remember the locations of the parts you removed to install them back easier.
Step 2: Clean the area and remove any deep-seated dirt, moisture, and unwanted elements before the installation of your new part.
Step 3: Attach the ?power' wire of your new harness to the positive terminal of the battery, and the ?ground' wire to a metal portion or the factory settings of your vehicle. If possible, connect it to the negative terminal of your battery.
Step 4: Plug the new socket into the bulb. Install the new relays and cover them with electrical grease to prevent corrosion.
Step 5: Turn your headlights on to check if they are working properly. If they are working without any issues, you did the installation task right. NOTE: Keep your headlight on for a long time, and try turning them on and off again and again to ensure you really did a good job.
