Painless Performance was founded back in 1990 as Perfect Performance Products and is currently a multi-faceted company with more than sixty employees in a modern 45,000 square foot facility. Painless wiring harness was the first product manufactured and offered by Painless Performance. As the word spread about its quality and ease of installation, it brought the company great popularity in the industry. Over the next few years after its foundation, the company grew rapidly, constantly developing innovations and expanding its lineup.

Today Painless Performance is recognized as a respected brand of automotive electrical systems and components, fuel injection management systems, and diesel performance products manufactured for car, truck, off-road, and racing markets. Available for dragsters, rock crawlers, etc., Painless Performance products offer a truly painless installation, while delivering reliable and lasting operation. The company uses only the highest quality TXL (Thermal Cross-Linked) wire to ensure its wiring harness resists high engine compartment heat.

At Painless, they realize that the quality of the wire or crimps makes no sense, if the wiring harness is designed with incorrect lengths of wire or improper gauges, because poorly engineered harness will be a nightmare to install. The company’s engineers take each project seriously, supervising each stage of production to make products that fit great and can be easily routed. The use of the latest diagnostic equipment and AutoCAD ensures that each Painless wire is drawn to its correct length and proper gauge is determined. If the harness is vehicle specific, this means that the wire is most often of the same length as the factory one, but the gauge of the wire will be increased to make it possible for you to install higher amperage accessories.

Painless Performance bends over backwards to guarantee that your wiring harness will work after installation, so that your lights will shine bright when you turn them on and your engine will start. Before it goes in the box, each and every fuel injection harness offered by the brand is pretested, being mounted on the test board to ensure that all connections are operating properly and there is continuity in all wires. Skilled craftsmanship is packed inside each wiring harness the brand manufactures. But you won’t see it unless you install Painless product in your automobile. You will undoubtedly appreciate how meticulously the company’s experts have grouped the wires in sections, thus helping you to drastically reduce installation time and avoid routing errors.

Every Painless wiring kit includes all fuses, relays, wire ties, flashers as well as mounting brackets needed to do the job right. To guarantee customers get nothing but trouble-free performance, every chassis harness that comes out of the box features the wiring already hand terminated to the Painless fuse block, while a Painless wiring switch panel delivers excellent protection from voltage and amperage spikes. With a strong commitment to perfection, the company never rests on its laurels and keeps developing innovations that set standards in the industry. Being absolutely confident in quality of its products, Painless Performance backs its harnesses with a lifetime guarantee.

Replacement Ignition Switch
Painless Performance® - Ignition Switch with Keys
It appears to be a well made and long lasting ignition switch. Keys could be a little more glamorous, company key chain welcome. Installation in my old ford was troublesome, but not the switch's fault in any way. A good product.
