Gm Wiring Harness Color Codes

By | January 13, 2023



When it comes to wiring harnesses and their various color codes, the General Motors (GM) brand has set the bar in automotive manufacturing for many decades. With a long history of innovation in this field, GM has become a leader in vehicle safety and reliability. The use of color-coded wiring harnesses is one of the ways that GM has achieved this success.

Color-coding wire harnesses provides an easy way for technicians to identify the function of each wire. This ensures proper installation and maintenance of GM vehicles. Knowing the color codes for GM wiring harnesses can also help to prevent costly errors during installation and repair. In this article, we will discuss the GM wiring harness color codes and how understanding these codes can benefit technicians and vehicle owners.

The GM wiring harness color code system begins with seven main colors. These colors are black, white, yellow, red, blue, orange, and green. Each of these colors has a specific meaning and purpose, so it is important to pay close attention to the color of any particular wire. Black wires are usually ground wires, while white wires are usually neutral. Yellow wires are usually used to connect the battery to other electrical components. Red wires are typically power wires, and blue wires are often used for steering wheel controls. Orange and green wires are often used for speaker systems.
