Rear electrical centre 701 (REC) |
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)
4D to roof harness 5D to roof harness |
5. |
Head 2 (in diagram = H2)
4D to roof harness 5D to roof harness CV to main wiring harness |
6. |
Rear (in diagram = R) to rear wiring harness
|
7. |
Tail (in diagram - T) to:
4D: parcel shelf harness 5D: rear 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
