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.

I installed the 69/70 Mustang harness into my 1970 Mustang fastback. I have to say that Painless Performance really got this harness right. The harness went in easily and fit better then the OEM harness. They provided plenty of fasteners and connectors to easily complete the entire installation. I really thought this was going to be a PAINFULL experience but to my surprise it was not!! The new harness provided for additional circuits and has incorporated into it for more modern technologies. I also installed an MSD, Mallory Unilight and OEM HOOD TACH which required additional wiring to get everything working. Along with the well written manual, their Tech support was able to help me with the additional connections. My old harness was a fire waiting to happen. I had circuit that did not work due to shorts and frayed and cracked insulation requiring me to tape everything which made the harness look horrible. I also added the wire cover for looks and wire protection. The car runs great and the harness is performing perfectly. I am so glad I decided to replace my old harness with a PAINLESS!!!
