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
Kelly Snapp

I have installed a 5.7 vortec w/ a 4L60 in my 76 Chevy K10 truck and it was a relief after looking at the jungle of wires on the donor truck and then looking at the painless kit. It made it very easy. After seeing my old truck run the way it did when it was finished, a friend decided to swap a vortec in his 72 K20. I assissted him somewhat with this, and this was also very easy and trouble free. You supply the good, working engine and components and Painless does the rest.Close Quote
