Painless Performance Products
Celebrating 25 years as the leading manufacturer of automotive electrical systems, fuel injection management systems, electrical components, and diesel performance products serving the classic car and truck, off-road, diesel, and racing markets.
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.
More than circuits and wire!
A wiring harness is, first and foremost, engineering. At Painless, all of our harnesses are designed by real engineers to ensure consistency in manufacturing and an accurate and easy installation.
Half the work is done for you
You'll appreciate how we take the time to properly group each wire in sections, drastically reducing the amount of time it takes to install a harness and virtually eliminating routing errors.
Pre-tested for guaranteed performance!
When you install a Painless harness, we GUARANTEE it is going to work.
