Looking beneath the hood of your car can be a daunting task for the novice mechanic. What might look like an incomprehensible mess of wires and metal can actually be a logical, orderly system that alerts you to potential problems in your car’s electrical system. If you understand the numbering system used for the wiring terminals, you can make heads or tails out of the disarray of wires and metal.
Car terminals are integral parts of the car's electrical system. They usually come in two different forms, spade and ring terminals. These components are responsible for taking the electricity from either a relay box or a wiring harness and transferring it to the right location within the car. To identify these locations, car manufacturers use specific numbers on the terminal which correspond to the part in which the electricity is being transferred. Each number corresponds to a specific area or component within the car’s electrical system.
Understanding the numbers is not as difficult as it may seem. Each number is unique and typically, if you break it down, you can determine the part where the power is going. For instance, a 6-digit number indicates the part where the power is flowing, such as the switch, relay, solenoid or voltage regulator. A 4-digit number is a bit more specific and focuses more on the area or component such as the fuse, bulb, etc. The two digits at the end of the code typically indicates the type of terminal, such as a resistance or ground terminal.
By understanding the wiring terminal numbers, you are better equipped to diagnose any issues with your car’s electrical system. Thorough knowledge of how the car is wired can save you time and money when you find yourself in a situation that requires you to troubleshoot a problem. So before you take it into the garage, take a look at your car’s terminals and get better educated on the numbers seen on the wiring so you can make sure the job is done properly.
