Distribution
On the following pages you will find parts of the electrical diagrams that always show only one specific design group of the car. The purpose of such a distribution is to save space. After all, the area of the windshield wiper system concerns both the Audi-100 with a 74 kW engine and the car with a 128 kW engine. So choose the section that you are going to work on at the moment.
Construction
The wiring diagrams are divided into many circuits, numbered at the bottom of the diagram. This way, based on the explanation of the wiring diagram, you can easily find the individual elements. The bottom line represents the "ground" of the car (that is, the body metal), through which an electrical circuit is closed. The grey area at the top of the diagrams shows the central switch. The designation of the plug contacts tells where the wire is connected. Example: S3/1 means that this wire should be found in the multi-pin plug S3 at connection 1 of the central switch.
If a wire ends in a rectangular box with a number in it - for example, 15 - then you will find the continuation of that wire in the named electrical circuit number, in the example it is circuit number 15.
Wire colors
In electrical circuits, the colors of the wires are given as abbreviations. The abbreviations mean: (bl) ch — blue; (br) k - brown; (ge) zh — yellow; (gn) z — green; (gr) cf — gray; (li) l - purple; (ro or rt) kr-red; (sw) h — black; (ws) b — white.
For which models?
On the following pages you will find a complete wiring diagram for the Audi 100, 1993. The wiring diagrams for the engine describe a 6-cylinder engine with an MPI injection system. Additionally, wiring diagrams for other engines are provided in the conclusion, which should be mentally integrated into the complete wiring diagram mentioned, if necessary.
Finally, there are wiring diagrams for additional equipment elements, such as the central locking system, electric windows and additional instruments.
