Knowing the meaning of car electrical wire colors is important. Especially if you want to delve into the automotive world intensively. The meaning of car electrical wire colors is somewhat difficult to read in a conventional way.

This is because the colors of car electrical wires are usually symbolized by specific codes. In this article, we will try to decode these codes. Who knows, it might help you understand the meaning of car electrical wire colors. For more details, you can just check below!

Meaning of 1 Color Car Electrical Wire

Car electrical wires usually come in one or two colors. Whether one or two colors, each has its own meaning. This time, we will first reveal the code for one-color car wires.

One-color wires in car electrical systems are usually wires with a fairly good electrical path. There are 15 codes for one-color car electrical wires. Those 15 codes are:

B : Black PU : Purple

BR : Brown R : Red

G : Green SB : Sky Blue

GR : Grey SI : Silver

L : Blue V : Violet

LG : Light Green W : White

O : Orange Y : Yellow

P : Pink

Among these fifteen colors, fourteen of them have their own functions. The functions of these colors are:

Starting and Ground : B (Blue)

Charging System : W (White)

Power/Lighting : R (Red)

Instrument Panel : Y (Yellow)

ECU/Sensor Signal : BR (Brown), G (Green)

Other : L (Blue), LG (Light Green), O (Orange), GR (Grey), P (Pink), SB (Sky Blue), V (Violet).

Meaning of 2 Color Car Electrical Wire

Two-color wires are car electrical wires that have two colors of insulation. The first color is the base color of the wire itself. Meanwhile, the second color is the marking (stripe) of the first color. There are four codes for this type of electrical wire. They are:

W-R : White-Red

L-W : Blue-White

R-B : Red-Black

G-B : Green-Black

Functions of Car Electrical Wires

Before this article concludes, we will explain the overall function of car electrical wires. Who knows, it might refresh your memory about the function of this car component.

The main function of electrical wires is to connect one component to another. Besides in cars, electrical wires are also commonly found in motorcycles.

Car electrical wires have several components. These components are:

Conductor

The first component in car electrical wires is the conductor. The function of this component is quite simple, which is to conduct electrical current.

Outer Protection

This component serves to provide protection to the car electrical wires. With this component, the wires will be protected from chemical influences, mechanical damage, or other things that could potentially damage the wires.

Insulator

While the previous component protects the wires, this component will protect the conductor. With this component, one conductor will not connect with another. This component can also prevent current leakage.

Knowing the meaning of car electrical wire colors is important. Especially if you want to delve into the automotive world intensively. The meaning of car electrical wire colors is somewhat difficult to read in a conventional way. 

Fortunately, we have informed you of the meanings of those colors. Thus, you can understand them more easily.
