1979 Trans Am Wiring Schematic

By | April 3, 2023



The Pontiac Trans Am is a true icon of American muscle cars. Its sleek design, powerful engine, and roaring exhaust have captivated car enthusiasts for decades. But what many people don't know is that the 1979 Trans Am also had a revolutionary wiring schematic. In this article, we'll explore the intriguing history and innovative features of the 1979 Trans Am's wiring schematic.

Back in 1979, General Motors introduced the Electronic Control Module (ECM) for their vehicles. This was a major breakthrough in automotive technology, as it allowed for more complex engine control systems. And the 1979 Trans Am was one of the first cars to use this new technology. The ECM was a small computer that controlled various aspects of the engine, such as fuel flow, ignition timing, and emission control. This meant that the engine could run more efficiently and with better performance. And all of this was made possible by the sophisticated wiring schematic of the 1979 Trans Am.

But what set the 1979 Trans Am's wiring schematic apart from other cars of its time was the use of a custom-designed "firewall" harness. This unique wiring harness ran through the firewall and connected the engine, transmission, and other key components to the ECM. This not only reduced the number of wires needed but also made repairs and upgrades easier. And with the help of this advanced wiring schematic, the 1979 Trans Am became a true powerhouse on the road.

In conclusion, the 1979 Trans Am may be best known for its stunning looks and impressive performance, but its wiring schematic is what truly set it apart. The introduction of the ECM and the custom-designed firewall harness revolutionized the way engines were controlled and paved the way for future advancements in automotive technology. Today, the 1979 Trans Am remains a beloved classic, and its groundbreaking wiring schematic is just one of the many reasons why.
