Voltage supply
When a transmitter/receiver unit is retrofitted in the vehicle, the battery is used for connecting the positive and negative wires.
In addition, the wiring harness must be manufactured:
t  Positive voltage supply via a red wire with 2.5 mm2 cross section.
t  Negative voltage supply via a brown wire with 2.5 mm2 cross section.
The positive wire must have a fuse located in the immediate vicinity of the battery. For this purpose, a fuse holder must be secured next to the battery. Both wires must be enclosed in an insulating tube.
Appropriate connections must be attached to wires on the battery side.
Proceed according to unit's operating instructions on side of unit.
The additional wiring must be routed separately from vehicle wiring, and a distance of at least 10 cm must be maintained.
  Note
t  Some telephone systems and two-way radios require an additional terminal 15 (ignition). In this case, a black wire with 1.5 mm2 cross section must be laid from the transmitter/receiver unit to terminal 15a. → Current flow diagrams, Electrical fault finding and Fitting locations
t  When laying the wiring, ensure that wiring is not routed parallel to factory wiring.
