No one likes fumbling with confusing wiring. It's bad enough with an aftermarket stereo, and is an absolute nightmare when dealing with chassis, fuel system, or engine wiring. Painless Performance has truly earned its name with products that make wiring simple for even the most inexperienced of us, giving professional-level results each and every time.

If you've been wanting to install a late-model fuel-injected drivetrain into your classic vehicle, Painless Performance makes it easy. Whether you're going with throttle body injection or the latest LS7 monster engine, Painless has the harness and accessories you need for a seamless installation, including custom flash programming once you have installed your harness and full compatibility with your manual or computer-controlled automatic transmission.

While it's true that there are a lot of wiring harness kits and accessories available in the market, there aren't many, if any, that are as easy to use as Painless Performance. We've actually purchased wiring kits that were less expensive than Painless, hoping to save a few bucks, but after purchasing all of the plugs and connectors needed for the installation, we really didn't save much money. In fact, we probably spent more money on gas chasing down the parts that would have been included with a Painless kit than we would have spent just by going with Painless in the first place! So whether you're wiring up a fresh hot rod build, or swapping in a late-model engine into your classic truck, Painless Performance will keep your ride on the road.
