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.

Great Part! I love the function of the key on/off relay circuit as well. Worked great in my Cummins Swap on my Ford Pickup. It has a great number of places to pull fused power from. The seal unit is bullet proof!Close Quote

The All New Painless Catalog is Available!

We're excited to announce that the all new Painless Performance product catalog is complete! The catalog can be viewed (and downloaded) on our website and we're also accepting orders for the print version that will be mailed out by the end of the month.

  When we say "all new" we mean it! Every product was photographed and we put together fresh, detailed product descriptions for each harness. We set out to answer all of the questions about wiring harnesses and our accessories to make a buying decision painless for our customers and dealers. In fact, each harness receives a full page description and breakdown of every circuit and accessory available on that particular harness.    

  One reason for the new descriptions is that Painless has updated all of our harnesses to include more circuits! This has been an ongoing process within our R&D team and we're excited to finally announce the results of these efforts. The original 12-circuit harness is now supplied with 21-circuits while the original 18-circuit harness is now available with 28-circuits! These changes have been available and shipping without fanfare or description updates so you can rest assured that any new harness has already been upgraded and is on the shelf at your favorite speed shop.
