HARNESS, Highway Series, Highway 22 Circuit, a complete wiring system that fits any car where basic operational circuits are the key, American Autowire

The Highway 22 harness system has long been the flagship universal system for wiring high-tech, high-end custom vehicles. To raise the bar to the next level, American Autowire is introducing the Highway 22 Plus! The goal? To preserve the same feel as the original, with some modernization and ease of use improvements for both backyard and professional builders.The new Highway 22 Plus combines some of the original features of the Highway 22 harness below: G-10 composite panel base measuring 7.5L x 4.5W x 3.125H, and nylon 6/6 panel components. GXL/XLPE GM color-coded wire. Easy-to-read wire labeling every 3- 4. Battery and accessory power expansion via heavy duty power studs on the panel. Self-locking screw clamp interface. American Autowires signature gauge cluster disconnect. Ignition, headlight and dimmer switches are included. Full-color, tabloid-sized, step-by-step instructions.The new features of the Highway 22 Plus include: Each kit will now include a built-in LED flasher to support LED turn signals without the need to purchase an additional item. Weve added back up light feed and power wires to make the harness easier to install in a more modern vehicle. The pre-installed 20 amp relay can now be easily changed to function as either a keyed 12 volt or ground triggered item. Weve improved 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. The wiper circuit has been upgraded to a 20 amp fuse to support all aftermarket wiper systems. This has been made an accessory circuit for more adaptability. The AC/Heat fuse has also been moved to an accessory circuit to eliminate draw from the blower motor while the vehicle is being started. All kits will feature 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 6 gauge wire and two 175 amp Megafuses. Extra connectors and wiring have been added to more easily support a 4-headlight system without an additional add-on purchase. Longer neutral safety wires for cars with console shifters.

Highway 22 Plus Series Wiring Harness, American Autowire

Great wiring kit! I have used painless wire and now this to completely wire a car. Painless instructions are a little more detailed although this American Wire kit gives good instructions and allows for way more custom applications. Also, everything from NPD is great quality, ships fast and packaged perfectly. Always listen to the Muscle Car Podcast where I have learned about how NPD sources products and why the quality is above other retailers.
