Guaranteed Painless Performance

Painless Performance Building in Fort Worth


If you're looking for superior quality, engineering and craftsmanship, Painless is your only sensible choice. Painless has remained the leader in automotive wiring and electrical products for 33 years through engineering and innovation, not corner cutting and imitation.


It's a lot more than circuits and wire!

How often have you seen advertisements for wiring harnesses promising, "21-circuit kit for the low, low price of...?" What do you get for that low price? 21 circuits and yards of colored wire? Is that all you need, and exactly what makes up a proper wiring harness, anyhow? Well, it's a lot more than just circuits and wire. A wiring harness is, first and foremost, engineering. 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.


Half the work is done for you.

The next most important component in a wiring harness is skilled craftsmanship. No, you won't find that in the box along with the parts kit, but you'll recognize it as you install one of our harnesses. You'll appreciate how we take the time to 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 the amount of time it takes to install a harness and virtually eliminating routing errors. That's why we say: With Painless, half the work is done for you.


Pre-tested for guaranteed performance!

Finally, and certainly not least, there's quality. You deserve the assurance that after installing a harness it's going to work: That when you turn on the headlights, they shine; That the blinkers blink and that the engine starts. Every single fuel injection harness, before it goes in the box, is mounted first on a test board. Each connector on the test board simulates a particular engine function. This test ensures that all connections are working properly, all pinouts are correct and there is continuity in all the wires. When you install a Painless harness, we GUARANTEE it is going to work.
