The car has certain earthing points which have "component numbers" and other earthing points at which the component is earthed directly to the chassis, such as temperature transmitters, oil pressure transmitters, etc. The locations of the earthing points with component numbers are the same in the Combi Coupe, the Sedan and the Convertible.

3 Earthing point in the fascia
7 Earthing point on the radiator cross-member
9 Earthing point in the luggage compartment
65 Earthing point under the back seat
93 Earthing point on the amplifier
117 Earthing point between the ignition switch and the handbrake lever
158 Negative distribution terminal in the electrical distribution box
201 Earthing point, engine (two)
211 Earthing point, gearbox
257 Earthing point, alternator bracket
300 Earthing point, brake unit
334 Earthing point for the airbag electronic unit
400 Redundant earthing point for the airbag electronic unit

The battery is earthed by means of a 16 mm(squared) conductor to earthing point 7. The engine is connected directly to the negative pole of the battery by means of a 25 mm(squared) conductor.

From earthing point 7, a cable then runs to distribution terminal 158 in the electrical distribution box on the left-hand front wheel housing.
