Some Painless Performance electrical wiring kits include chassis harnesses and EFI harnesses for General Motors, Ford and Jeep. Painless Performance manufactures electrical systems, electrical components for classic car, truck, off-road, diesel and racing markets.
Painless Performance prints the purpose on every wire in the chassis harness kits in contrasting inks to produce vivid labels every few inches. Each harness kit contains all necessary components, including fuses, flashers, relays and mounting brackets. The manufacturer sends the harness kit already wired, leaving the mechanic to mount the block and route the wires.
Painless Performance allows the consumer to customize a harness kit by answering a few simple questions, including selecting the vehicle type, where the ignition is mounted and if there are electrical accessories such as power windows.
