Highway 22 Plus Panel Wiring Kit
Highway 22 has long been the flagship universal system for wiring high-tech, high-end custom vehicles.
To this point, American Auto Wire has seen and heard evidence of customers installing the kit in just about every make or model vintage (and some modern) vehicle, off-road trucks and even industrial equipment.
We’re exceptionally grateful to be part of so many builds, and have taken note of some suggestions from over
the years to make a great product even better. With those thoughts in mind, American Autowire is pleased to
introduce the Highway 22 Plus!
The goal with the changes in the Highway 22 Plus is to preserve the same feel as the original, with some
modernization and ease of use improvements for both backyard and professional builders.
The full list of new features is below:
• Each kit will now include a built-in LED flasher to support LED turn signals without the need to purchase
an additional item.
• 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.
• We’ve 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 ga 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.
These original features that made the Highway Series the most popular wiring system available are still part
of the new Highway 22 Plus:
• G-10 composite panel base measuring 7.5”L x 4.5”W x 3.125”H, 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 Autowire’s signature gauge cluster disconnect.
• Ignition, headlight and dimmer switches are included.
• Full-color, tabloid-sized, step-by-step instructions.
