Painless Performance Products has been in the performance market for almost two decades, offering painless solutions to automotive wiring, such as wiring harnesses, computer chips/modules, engine management systems, electrical switches, and panels.
Each product is designed by an expert engineering team and tested with cutting-edge diagnostic equipment to ensure optimal performance.
All harnesses are designed by real engineers using the latest diagnostic equipment and AutoCAD to ensure consistency in manufacturing and accurate, easy installation.
You deserve the assurance that after installing a harness, it will work: when you turn on the headlights, they shine; the blinkers blink, and the engine starts.
A Painless fuel injection harness is shown on our exclusive test board.
Every fuel injection harness is mounted first on a test board like this before it goes in the box, with each blue connector simulating a particular engine function.
