Highway 22 Plus Wiring System
Twenty two circuits. One panel. Any build. The Highway Series earned its name by being the harness a first timer could finish and a pro would still pick. The Plus keeps that feel and builds in the parts people kept buying separately. The LED flasher is in the panel; so LED turn signals work without hunting for an equalizer. Back up light feed and power wires are already run. The 20 amp relay sets up keyed hot or ground triggered without cutting anything. The wiper circuit moved to a 20 amp accessory fuse so an aftermarket wiper motor stops popping fuses; and the AC/Heat fuse moved to accessory so the blower is not fighting your starter on a cold morning. Every kit now ships with the high amp alternator and main power kit - 6 gauge wire and two 175 amp Megafuses. That is the detail you appreciate the first time you crank a big alternator and nothing under the dash gets warm.
Install Level: Intermediate - full vehicle rewire; universal harness needs routing and trimming
Universal system. It is not pre-cut to a specific chassis.
Gauge cluster disconnect is built into the panel.
Our 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. Each kit will now include a built-in LED flasher to support LED turn signals without the need to purchase an additional item. We’ve 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.
We’ve also 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.
