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.

After using other products to "try" to make dual electric fans work like a stock car's I got very frustrated. There are plenty of controllers for single fans but Painless' 30140 F5 Dual Fan Controller is the BEST I have seen for this application. The 30140 was designed for dual fans and it works GREAT! The fans start up gradually and it does not spike my system or dim my headlights with an additional 70 amp draw. The installation wass simple and the system operates flawlessly. My 68 Vette with it's Big Block stays nice and cool at all times. The parts are of the highest quality and the directions are clear and easy to follow. Heed the advice about locating the controller and put it in the car if possible, Engines with headers get Hot and the max of 257 degrees is hard to hit under the hood in the summer. If you are using dual fans don't use two controllers. It is Painless this way!Close Quote
