The Highway 15+ is the smaller, 15 circuit version of our flagship Highway 22+ universal system. Designed for builds that don’t need a massive fuse panel but still demand reliability, it features 15 fully labeled circuits, high-temperature GXL wiring, and a compact, modular fuse box for clean routing in tight spaces. perfect for street rods, kit cars, and roadsters where simplicity meets professional performance.
Features include:
- A built-in LED flasher to support LED turn signals without the need to purchase an additional item.
- A back up light feed and power wires to make the harness easier to install in a more modern vehicle.
- Improvements to our instructions to cite a wider range of examples and real-world scenarios. The panel labeling has also been updated along with the above physical changes, including wording modifications for enhanced clarity.
- Our new high amp alternator and main power connection kit. This allows for the use of high amp alternators, and provides an even better level of fuse protection for the panel and charging system. This new connection kit utilizes 6ga wire and two 175amp Megafuses.
- Extra connectors and wiring to more easily support a 4-headlight system without an additional add-on purchase.
- Longer neutral safety wires for cars with console shifters.
- An additional ignition circuit to support aftermarket components.
- Improved ignition switch with mating connector and 4 additional accessory and ignition terminals. Uses a square GM-style key.
