Why Choose a Painless Harness?

Quality Harnesses


Number One Selling Harnesses For The Best Reason: Quality!

Our customers know that installing one of our harnesses is truly a painless experience. Install just one Painless chassis harness and you'll be a customer for life. Yes, you can buy a cheaper harness, but why would you? The time and effort that goes into building a project vehicle should not be jeopardized by using an inferior electrical system. All wires are not created equal.

When it comes to the safety of your vehicles electrical system, cutting corners when it comes to the wiring system is just not a good idea. With nearly a quarter century of experience and a quarter million harnesses on the road, Painless is the sensible solution to all your automotive wiring needs.

Painless Customer
Bruce W. Smith

We used your 4 rocker universal panels and relay kits for our 2007 Toyota Tundra Project Deepwoods at Off-Road Adventures magazine. They worked great--and saved us a lot of time. Here's what i said: Speaking of wiring, Deepwoods has a lot of extra wiring and switches. We utilized a couple switch and relay kits from Painless Performance Products to make the job, well, painless. Note we didn’t say quick; adding switches and running the wiring in any project vehicle is tedious if it’s done cleanly. For example, we used a pair of Painless four-switch wiring kits, complete with all the wiring, and a relay kit to control all of the auxiliary lights, spare battery, on-board air system, and rear power supply. The two switch panels were installed in our Tundra’s overhead console with the Painless Performance color-coded and labeled wires running from the switch banks between the headliner and roof, down the driver’s side “C”-pillar to the door sill kick panel where they connected to the wires coming from the battery, lights, and other accessories. No easy task. But the end result is really sick. And when you have a wiring kit and switches already to use, like those from Painless, the job is that much easier and well done. Close Quote

Not only are PowerBraid & ClassicBraid great for wires, but they also can be used around hoses, lines and other items throughout a build.
