American Autowire Highway 15 Plus Wiring Harness Kits

American Autowire Highway 15 Plus wiring harness kits are built upon the legendary Highway 15 Series harnesses. The goal of the Highway 15 Plus wiring harness kits is to preserve the same feel as the original, with some modernization and ease-of-use improvements for both backyard and professional builders. Below are the new features added to the Highway 15 Plus Series wiring harnesses. New features: * 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 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 * A 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. The new connection kit utilizes 6-gauge wire and two 175 amp mega fuses * 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 four additional accessory and ignition terminals.
