Your vehicle relies on various wire connectors in order to function properly. Whether you're upgrading your car's entertainment system or fine-tuning the power train system, you need high-quality wiring and connections. This is why it's important to consider some factors first before buying replacement or aftermarket connection kits. To help you out, here are some tips:

1. Take a close look at your vehicle's wiring systems.

Before you purchase a connector, make sure to familiarize yourself first with the type of wiring system your car uses. Keep in mind that the right type of connector will depend on where it will be attached. Since electrical wires on your vehicle's entertainment system, power train, chassis, and lighting units all use a variety of connector kits, better check first with the manual or the manufacturer which kind of connector is best used on certain types of wires.

2. Do your research on features worth splurging on.

Depending on where you use the connectors, these features are worth every dollar:

Matte-seal technology . This feature provides a tight water seal for wires that require high-grade waterproofing. Products backed by this feature are perfect for connections in the gear box, engine control unit, and other power train applications.

Color-coded wire . Because installing or replacing busted car wires can get confusing, color-coded connectors help you avoid attaching the wrong headers to the wrong wires. So if you want hassle-free installation, look for this feature.

Modular connecting system . If you want cost-effective connectors, choose a modular type because this is designed to fit different circuit sizes. This means you only need to use a single type of connector for a variety of circuit and harness sizes.

Twist-lock mechanism . Depending on the type of connectors used, you can link wires by using special fasteners. However, if you want a fastener-free installation, opt for a twist lock connecting system. Basically, plugs with this mechanism are locked in place by twisting it.no clamps or bolts needed. Plus, this type comes with visual, audible, and tactile features that effectively differentiate a locked and unlocked plug.

Specially reduced connector size . If you're replacing wirings for your vehicle's sensors, a specially designed connecting system with smaller wires is the perfect choice. This system is meant to fit smaller mating terminals, making it the ideal option for highly complex electronic assemblies used in parking, air bag, mass airflow, and radar sensors.

3. Opt for a connector with high corrosion resistance.

Before choosing a connector, make sure its materials can effectively resist corrosion even after years of use. If you can, take a closer look at a connector and see if the shell, pin retainers, pins, and sockets are made from thick and sturdy materials. A connector with flimsy looking parts should raise red flags about the quality, especially its resistance to corrosion.

4. Choose a vibration-proof connector when linking wires for on-board instruments.

When upgrading or replacing connecting systems for your car's shift lever or steering wheel, a vibration proof connector that can resist a pull force of at least 10 kgf (100 N) is a good option. Whenever you rotate the steering wheel or pull the shift lever, you'll know that the wires beneath these parts won't easily break or get unplugged even after years of use.
