Whether you’re working on a restoration or an engine swap, rewiring isn’t always simple. It can be a frustrating and tedious process. Painless Performance has products that make this process easier and less of a hassle. They’ll replace the old wiring for a clean, more modern look.

Painless chassis wiring harnesses are color-coded and labeled for a straightforward installation. The extra length allows for trimming and custom routing for hiding wires. These wiring harnesses let you safely rewire new aftermarket items or existing accessories.

Many of the factory connectors are already installed on the harness right out of the box. Painless also offers customizable universal wiring harnesses for Ford and Chevy.

If you're converting to electronic fuel injection, Painless EFI wiring harnesses can make the transition smoother.
