The perfect choice for tight spots in kit cars, roadsters and coupes.
The changes in the Highway 15 Plus preserve the same feel as the original Highway 15 Universal Wiring System, with some modernization and ease-of-use improvements for both backyard and professional builders. Made in USA.
New 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.
- High amp alternator and main power connection kit that allows for the use of high amp alternators, and provides an even better level of fuse protection for the panel and charging system. Connection kit utilizes 6 gauge wire and two 175 amp 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.
- Improved instructions 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.
These original features that made the Highway Series the most popular wiring system available are still part of the new Highway 15 Plus:
- G-10 composite panel base measuring 4.5"L x 4.5"W x 3.5"H, and nylon 6/6 panel components.
- GXL/XLPE GM color-coded wire.
- Easy-to-read wire labeling every 3"-4"
- Self-locking screw clamp interface.
- American Autowire’s signature gauge cluster disconnect.
- Ignition, headlight and dimmer switches are included.
- Full-color, tabloid-sized, step-by-step instructions.
