MAN TG3 Auxiliary Systems Wiring Diagrams – Electric Sun Blind, Tachograph & Tail Lift Control Systems

This technical wiring manual contains the complete electrical schematics for multiple auxiliary systems used in MAN TG3 trucks including the electrically operated sun blind, tachograph installation system and tail lift control wiring.

The diagrams include the full control architecture for sun blind motor assemblies, tachograph communication interfaces, tail lift control modules, relay control circuits, fuse protection routing and electrical supply connections.

All circuits include connector identifiers, system references and grounding architecture required for professional diagnostics, repair or auxiliary system troubleshooting.

Electric Sun Blind System Components

• Electric roller sun blind motor

• Sun blind control relays

• Driver UP and DOWN operating switches

• Central electrical system supply

• Fuse-protected sun blind circuit

These components form the electrical architecture responsible for windshield sunshade operation.

Tachograph System Components

• Tachograph control unit wiring

• Speed signal routing interfaces

• Power supply and ignition routing

• CAN communication interfaces

• Ground network references

These circuits support installation and operation of digital tachograph systems for vehicle monitoring and regulatory compliance.

Tail Lift Control Components

• Tail lift control module wiring

• Tail lift operating switches

• Electrical supply routing for lift operation

• Control signal wiring for activation and safety monitoring

These components provide the electrical architecture for rear tail lift operation and auxiliary body equipment.

CAN Bus and Electronic Communication

• Vehicle CAN communication routing

• Control module signal interfaces

• Auxiliary system data communication

• Monitoring signal transmission

The auxiliary systems communicate with vehicle electronics through CAN networks for monitoring and safe operation.

Electrical Supply and Ground Routing

• Terminal +30 fused electrical supply routing

• Central electrical system power distribution

• SYS_groundNet grounding references

• Auxiliary electrical harness routing

These protected circuits ensure stable operation of all auxiliary electronic systems.

Wiring Harness Interfaces
