Der Schaltplan zeigt schematisch die Komponenten der elektrischen Anlage, die Funktionen und die Stromverläufe an.

In der Betriebsanleitung, die jedem Fahrzeug einst beilag, ist der Schaltplan im Format A5 abgedruckt, aber wegen dem Massstab und der einfarbigen Unterlegung nur schwer lesbar. Im Werkstatt-Handbuch ist der Schaltplan besser lesbar, da er dem Format A4 angepasst ist.

In der Tabelle ist angeführt in welchem Werkstatt-Handbuch die Schaltpläne abgedruckt sind.

Für die Modelljahre 1961 bis 1969 gibt es nur vier unterschiedliche Schaltpläne. Der Sicherungskasten enthält nur drei Schmelzsicherungen mit je 35 Ampere.

Bei den Modellen mit der D-Jetronic werden die einzelnen Komponenten durch 12 Schmelzsicherungen in unterschiedlicher Nennstromstärke gesichert.

Artwork by Warren Townsend - 2019 - Melbourne Australia - Available for free use in the classic Volvo community
Based on an original Swedish Design Concept of the 1960s and 70s.

I have attempted to make these Wiring Diagrams as accurate as possible, however no responsibility is accepted for any consequential errors from their use.In some instances Volvo made mid run production changes, please also reference previous, or subsequent year's schematic.

Update April 2022 for P1800 and 1800S: I have updated the Wiring Diagrams to include detail for wiring on MY64 Tachometer – to show the separate Rev Counter Unit on cars up to Ch # 10000.
Minor changes to Tachometer wiring is also shown with the Induction Loop Tachometers on MY64 through to MY69.

Update March 2022: Corrections have been made to wiring circuits for BW 35 Automatic Transmissions.
Switch Terminal numbers have been added to the Headlight Dipper Switch across the P and S cars.
Changes have been made to the Interior Light - Door Switches - to be consistent across all Model Years (now showing circuit with doors closed).
Terminal designations have been added to additional Relays, for clarity.

Update February 2022 for P1800 and 1800S: Simplified Interior Lighting circuit which more clearly reflects the wire layout on the cars and Interior Lights with switching integrated in the lights.
Horn Wiring circuit has been modified on 1961 through 1964 cars to reflect actual wiring on the cars (actual wiring was different to the original schematics).
Wire colours on the Over Drive circuit modified based on feed back from owners of 1965 – 1969 cars.

The PDF files can be printed in any format or as a cut-out.

Warren Townsend, thank you very much!
