A Guide To Understanding Automotive Electrical Connectors & How To Clean Them


Automotive electrical connectors are made especially for use in electrical systems in automobiles. Automobile systems have evolved dramatically, and today’s systems are heavily wired and powered by a microprocessor. The demand for high-quality, dependable wiring and automotive electrical connectors has risen as a result. When choosing automotive electrical connectors for your car, think about the current ranking, circuit density, wire size, voltage, configuration, and engagement force.

Power windows, alarms, radio receivers, relays, lighting, and ignition systems are among the other vehicle parts that need electrical cable connectors.

Automotive Electrical Connectors Are Categorized Into The Following Categories:

  • Environmental pollutants are prevented by using multi-pin sealed connectors.
  • Unsoldered connections are made with terminal connectors.
  • Wire-to-board connections are used to link various components to the computer’s circuit board.
  • Board-to-board connectors are used to link two circuit boards together.
  • Wire-to-wire electrical connectors are used to link two wire-terminated cables together.
  • Automotive Electrical Connectors

Automotive Electrical Connectors Of The Distribution Kind-

These vehicle electrical connectors can be used in amplifiers and ignition boxes, and come in a variety of sizes and lengths.

8 AWG Wire-

The big AWG distribution-type connectors are colossal in size and capable of handling massive currents. When working with larger cables for charging systems, however, you’ll need additional electrical tools like cable cutters, crimp tools, battery clamps, distribution blocks, and a propane gas torch.

In race cars, AWG Wire 8 and larger connectors provide a fast link between the battery and charger. For passenger cars, all automotive electrical connectors are usually designed, tested, and assembled according to ISO requirements. So they are completely safe to use.

Corrosion can be a problem with automotive electrical connectors, particularly those that are exposed to the elements obstructing the flow of electricity, resulting in the failure of the system being operated. Since most outdoor electrical connectors are small, a small diameter metal brush may be required. You can remove the corrosion and strengthen the link by using a simple procedure.

Connectors for Males-

  • Phase 1: Follow the manufacturer’s instructions for connecting a memory saver device to the car. Using a battery wrench, and disconnect the negative battery cable.
  • Phase 2: Using the clean cloth, wipe the connector to remove dirt or debris. Pull the connector apart to reveal the male probes or pins and the female socket. Examine the male pins for wear and tear. Corrosion is shown by a green or whitish coating on the pins. The entire plug assembly can need to be replaced if the metal appears rusted and broken.
  • Phase 3: Tear a small piece of fine sandpaper, about one inch wide by two inches long, from the roll. To remove the metal discoloration, buff or rub the pins with sandpaper. The pin can be wrapped in a small piece of sandpaper. Rotate the paper until you see a smooth and shiny metal surface.
  • Phase 4: With the toothbrush, clean the metal pins. Remove any dry dust or corrosion with a simple spray of the automotive electrical connector cleaner. If contact cleaner isn’t available, clean the pins with vinegar. Brush the pins once more to clear the remaining debris.

Apply a thin layer of contact lubricant with a spray gun. This will help to keep corrosion at bay while also increasing the connector’s conductivity.

For automotive electrical connector wires, you’ll need sturdy and dependable wire connectors and surplus electrical supplies. Find all types of automotive electrical connectors at a reputable retailer who carries high-quality labels and has a ready-to-ship inventory of terminal connectors and electrical cable connectors.
