The American Autowire Beetle Wiring Harness is a custom wiring harness and is not a factory replacement, direct fit harness. Specialized tools are a must, and a general knowledge of automotive electrical systems is recommended.
Modern Integrated Fuse Box with Built-in Relays
Complete Headlight to Tail Light Wiring Harness
XLPE Wire is Labeled every 3 inches or VW color coded
Fuse Protected Main Power Feed
The American Autowire 1962 to 1974 Standard Beetle & 1962 to 1970 Standard Beetle Convertible Wiring Harness comes with a modern fuse box that houses and includes a Flasher Relay, Turn Signal Relay and a Horn Relay as well as a headlight circuit breaker. The AAW harness is a complete, headlight to tail light, custom wiring harness that will modernize the wiring system in your VW. This replacement wiring harness is by no means a factory replacement harness. Running individual wires and terminating the ends and wires will be necessary. Some specialized tools are required and can be purchased or rented through AAW. The wiring harness hooks up to the original ignition switch, headlight switch, headlight dimmer/headlight relay and other factory electrical items. The AAW harness requires the use of the 1968 and later, 211953235A emergency flasher switch for 1966 through 1968 models with a 2 prong flasher switch. The harness is not compatible with 6 volt bulbs, your car must have a 12 volt system.
Our Expert's Take:
The American Autowire wiring harness isn't anything like the original VW wiring. Installing the harness requires general automotive electrical knowledge but rewards you with a modern, up to date electrical system that is safer than the original VW wiring. Re-wiring your VW helps alleviate so many of the common electrical gremlins that can cause headaches or worse, a fire. Whether you're choosing this harness or a factory replacement wiring harness, replacing the old wiring a VW should be a top concern during any restoration.

Wiring Instructions & Diagrams:
-AAW fuse box power & distribution panel has spring steel reinforced terminals and high strength screw terminal connections for the outputs.
-The fuse box panel uses standard ATC and mini ATC fuses along with Micro Relays for the Horn and Emergency Flashers. A standard relay is used for the turn signals and an electronic flasher is included for use with LED turn signal bulbs.
-AAW uses XLPE wire which is significantly more resistant to heat deformation, abrasion, chemical and stress cracks versus the PVC-coated original wiring.
-The harness works with the original VW switches and components. The main emphasis when creating the harness was on the use of original or available VW switches. A switch supplement is included that lists optional switches and the correct connections to these switches.
-Uses original .25 type terminals to mate to switches. Detailed connection drawings supplied for direct connections to all switches.
-A new directional light socket is required and included along with diode modules which isolates the left and right side turn signal circuitry. The new bulb socket allows LEDs to be used in the turn signal indicator.
-Correct terminal ends are included for the front headlights, turn signal and rear tail lights and license light for a direct connection to the housings.
-The headlight connections are pre-terminated.
-The harness is color coded at the steering column connections for turn signals.
-All the wires are either labeled with circuit description every 3 inches or use original VW wire color coding.
-The included instruction sheets contain a complete wiring chart use that identifies each circuit wire, color and function. The chart identifies the original VW circuit numbers and the modifications made by the American Autowire design. The American Autowire Main fuse panel identifies circuit and fuse rating.
-The engine wiring identifies connections to coil, oil pressure sender, generator and regulator, carburetor connections, starter, and includes optional wiring for engine temperature and tachometer if you want to run additional gauges. The connections are identified with VW circuit numbers as well as graphically.
-The main power feeds to the fuse panel are fusible link protected unlike the original VW wiring! 12 gauge wires are used for the main power feeds.
-The detailed instruction sheets are printed in color to identify specific functions and connections for each of the wiring sub-assemblies.
