What is Color Code for Harness?

There is no one “color code for harnesses,” as different manufacturers use different color schemes. However, there are some general guidelines that can be followed when deciphering the colors of a given harness. Generally speaking, the thicker the gauge of wire, the darker the color will be.

So, for example, a 14-gauge wire will typically be black, while a 12-gauge wire will be brown. Additionally, each individual wire within a harness will usually be a different color than its neighbor – this allows for easy identification and tracing of individual circuits.

What are the Wire Color Codes?

The standard for wire color coding in the United States is ANSI/TIA-568-C.2, which was last updated in 2011. This standard dictates that there should be a pair of insulated wires twisted together for each signal and one unshielded “ground” wire. The most common colors used are:

• Blue and white – Used for data signals (Ethernet) • Orange and white – Used for voice signals (telephone) • Green and white – Used for video signals (television)

Other countries have different standards; for example, the U.K.’s wiring code includes red as a fifth color to indicate fire alarm circuits. The main purpose of having different colored wires is to easily identify what type of signal is being carried by each wire so that they can be properly connected at both ends. For example, if you were to accidentally connect an Ethernet cable to a telephone line, it would not work because the two use different signaling methods.

What Color is the Wiring Harness Connector?

Most wiring harnesses have a standard color code. The colors used are usually black, green, brown, and white. There may be other colors used as well, but these are the most common.

Black is typically ground, green is for right turn/brake lights, brown is for left turn/brake lights, and white is for marker lights or running lights.

What Color is the Turn Signal Wire?

Most turn signal wires are colored green, yellow, or orange. The wire that powers the turn signals is typically a different color than the wires that power the brake lights and tail lights. This helps to prevent confusion when wiring up the system.
