Applications & Installation

The Builder 19 is designed for custom vehicles that require a universal wiring solution rather than a vehicle-specific replacement harness. Its compact fuse panel makes it especially useful for roadsters, coupes, kit cars, and custom builds with limited under-dash space.

Because this is a universal wiring system, installation requires adapting the harness to the vehicle's switches, lighting, instrumentation, charging system, ignition components, and electrical accessories. Additional connectors or wiring modifications may be required depending on the vehicle and equipment being installed.
