| Location |
The electrical centre is located in the luggage compartment on the left-hand wheel housing.
| Main task |
Act as the electrical centre for the rear of the car and the roof, and perform certain logic functions such as for the rear lighting.
| Type |
Electrical centre with relays, Maxi and micro fuses and an integrated control module for logic functions. Wiring for a trailer connector is connected to the electrical centre.
| Connect |
The electrical centre is fed with a +30 supply from the engine bay electrical centre (342) and grounded to grounding points G3 and G29. The electrical centre is connected to the wiring harness via 7 connectors:
| 1. | Body 1 (in diagram = B1) to main wiring harness | |
| 2. | Body 2 (in diagram = B2) to main wiring harness | |
| 3. | Body 3 (in diagram = B3) to main wiring harness | |
| 4. | Head 1 (in diagram = H1) to roof wiring harness | |
| 5. | Head 2 (in diagram = H2) to roof wiring harness | |
| 6. | Rear (in diagram = R) to rear wiring harness | |
| 7. | Tail (in diagram - T) to: 4D: parcel shelf harness CV: rear harness  | |
The connectors for the main, parcel shelf and rear wiring harnesses each comprise four connectors, which are named A, B, C and D in the wiring diagrams, for example B1-B.
The TR-WH connector is used for a trailer connector. In some cases a special module, TR-MOD, is required.
The electrical centre contains the following power circuits:
+30 power supply, rear electrical centre
+15 power supply, rear electrical centre
