Painless Performance - 30 Years of Automotive Wiring Solutions

Painless is proud to be celebrating 30 years of American made wiring solutions.  Thirty years ago, the first Painless wiring harnesses were manufactured in a tiny roll-up rental unit on the west side of Fort Worth. As word began to spread about these easy to install chassis harnesses, the legendary Tex Smith got word and, writing a positive review in his Hot Rod Mechanix magazine, ended it by saying, “Folks, this is really painless wiring!” The name caught on and soon Perfect Performance became Painless Wiring.

Today, Painless is headquartered in a modern 45,000 square foot facility in Fort Worth. All research and development, engineering and manufacturing is done in house. At Painless, we are and always will be American made, American proud, and American Strong.
