I'm becoming more and more interested in the wiring of my beetle as I contemplate launching into a project of adding gauges and electrical components and updating stuff. Before doing that, I need to understand the wiring as designed and implemented in the car.
As part of this process, yesterday I made a high-resolution scan of a copy of the wiring diagram for my car that I have. People have posted copies of the orginal wiring diagrams, but I wanted higher resolution versions, so that I can post modified versions.
Here's the main scan (reduced in resolution, of course):
One of the diagrams I wanted to produce was to highlight the wires in the car that are live, connected to the battery without fuses at all times.
Here's a partial diagram of the fuse box. Note the red wire that I indicated with a purple arrow. That's the main wire directly from the battery.
The other two red wires shown here are connected to the main battery wire with a metal strap, all on the unfused side of the fuse box.
Here are the actual wires in the car:
This diagram shows where those wires go in the car. From the fuse box on the left of the diagram, one red wire comes through the wiring harness from the battery that's at the right of the diagram (in the rear of the car). One red wire goes up to the light switch, the other goes down to the ignition key cylinder switch.
