8.6.8.1 Heater connection, control element
The electrical connection is to be made as shown in the
appropriate circuit diagram (see section 7).
To connect the wiring harness, remove the cover (see
9.2.1.1) on the heater and connect the wiring harness plug
to the control unit.
Before using the heater for the first time fit the cover to
prevent the illegal escape of hot air (heater overheating).
The wiring harness can be fed out of the left or right side
of the heater.

Ideally from the vehicle’s central electrical system.
An additional blade terminal fuse holder is to be fitted to
protect the heater (supplied with the heater). The fuse
holder may only be installed in the interior of the vehicle.
