Pre-wired • Economical Our newly updated POWER PLUS series is a complete Integrated Fuse Box Wiring System, combining a factory-style pre-wired fuse box with a new simplified installation approach. An Integrated Fuse Box System installation starts at the fuse box and each of the circuits are routed from the fuse box to their destination. By utilizing direct run technology to all major components with no disconnects, there is less work for you! In addition, Power Plus wiring systems now include new headlight and dimmer switches at no extra charge for your added convenience. We currently have two wiring systems in the line - Power Plus 13 and Power Plus 20.
