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.
