Warning The lines A5 and A6 must be wired for the correct operation. If the line A6 is not wired in the vehicle-side con-
nector cable, a connection (bridge) between A5 and A6 must be produced. Affected are especially vehicles with
12 V power supply.
In EFAS-4.10 (OE version) the following contacts are without internal connection: B5-B8, C1-C4, D3- D7.
