Understanding Track Style Wiring Diagrams, Important Stuff !
What the heck is a "Track Diagram"?
Volkswagens' "Current Flow Diagrams" or track scheme of wiring diagrams is truly one very large view of the electrical systems and components
incorporated on a particular vehicle. The "Engine Specific - Main Wiring Diagrams" or standard equipment diagrams, i.e. Tracks 1 - 308, will
contain all components starting from the battery and moving to the brake lights [optional equipment excluded]. However, since it would be physically
impossible to view all the tracks on one display or page, they have broken this large system of "Engine Specific - Main Wiring Diagrams" into
smaller Component related divisions. For example, "Battery, Starter, Generator and Voltage Regulator" may be found on "Tracks 1 - 14", and "Brake
Lights and Backup Lights" found on "Tracks 293 - 308". Optional/Common Equipment diagrams are added for systems or components which VW
does not consider standard equipment for a particular model, i.e. Air Conditioning, Traction Control, Central locking and Power Sunroof, to mention a
few. Optional equipment will vary from model to model.
It is very important to understand that track usage may appear to be duplicated or contain omissions; this is not a mistake!.
For example, while "Tracks 1 - 14" under "Engine Specific - Main Wiring Diagrams" may be used for "Battery, Starter, Generator and Voltage
Regulator", the same term "Tracks 1 - 14" can also be used for the optional equipment diagrams "Cruise Control" and "Heated Seats", since they
represent three separate diagram schemes.
