Use of electrical diagrams

This manual does not provide wiring diagrams for cars of each year of manufacture. But since the changes were usually small, the diagrams below can be used for all cars.

Below are the following wiring diagrams:

• wiring diagram of VW Kafer 1200/1200L cars produced since August 1975;
• wiring diagram of a VW Kafer 1303 from August 1974;
• wiring diagram of a VW Kafer 1200 manufactured in August 1974;
• additional wiring diagram for VW Kafer 1300/1303 produced from August 1974;
• additional wiring diagram (fog lights and rear fog lights);
• electrical circuit changes (generator and voltage regulator).

The electrical diagram clearly shows the path of current in the electrical circuits of the car. Schematic datasheets allow you to quickly trace the path of current through any circuit. In the diagrams, the lower gray bar indicates "mass" car.

Some electrical circuits and their constituent elements are listed separately. For clarity, the chains are shown one next to the other and numbered in order at the bottom, in a gray stripe. In the specification for the scheme, you can find the desired element of the scheme by its number.

Of course, the electrical circuit can also be used to solve the inverse problem. For example, in an electrical circuit, a wiring diagram with an unknown element is found. Then, in the specification, the name of the element is searched for the corresponding letter. In this case, letter designations are assigned to elements in a certain correspondence: for example, lighting lamps - L, control lamps on the instrument panel - K, taillights - M. Manual switches are marked with the letter E, mechanical switches - F, electric motors - V, and relays - J.


The following are the designations of the most commonly used elements of electrical circuits.

Connecting wires can be either single-color or multi-color. Wires of the same color almost always perform the same functions: red - "positive", brown - "weight" etc.

Small numbers located at the break of the wire lines indicate the cross-sectional area of the wire in mm².

The thin black line in the diagrams indicates the direct (without wires) contact of the circuit element housings with "weight". In the same way, the internal connections of the structural elements of the electrical circuit are indicated.

The remaining numbers and letters mean the following:

• the numbers below, in the gray strip, show the sequence number of the electrical circuit;
• black numbers in white circles indicate a specific pin or terminal number "masses", belonging to which is indicated in the specification;
• white numbers in black circles indicate the pin number of the diagnostic connector.

Wire color

Designation	Color
joint venture	blue
rd	red
up	green
S	black
wt	white
br	brown
ag	grey
VI	yellow

Note. Most wires are color coded. In this case, the color designation consists of four letters (for example, rd/wt is red with white marks, gr/gn is gray with green marks, etc.).
