Painless Performance Parts

It's a lot more than circuits and wire! At Painless, all of our harnesses are designed by real engineers using the latest in diagnostic equipment and AutoCAD to ensure consistency in manufacturing and an accurate and easy installation. You'll appreciate that we properly group each wire in sections so that instead of routing eighty or a hundred individual wires, you route entire sections of the vehicle at one time, drastically reducing installation time and virtually eliminating routing errors. That's why we say: With Painless, half the work is done for you.
