General safety and installation instructions
Warning! Inadequate cable connections can lead to short-circuits which cause
the following:
–
cable fires
–
triggering of the airbag
–
damage to electronic control equipment
–
electrical functions (blinkers, brake-lights, horn, ignition, lights) fail.
The following indications must be therefore considered:
When working on the cabling of the vehicle, the following terminaldesignations
apply:
30 (input from battery plus direct),
15 (switched plus, behind battery)
31 (return cable from battery, earth)
58 (parking light)
–
(back-up light)
The securest form of connection is obtained by soldering the cable ends and then
insulating the connection.
For releasable connections, use only insulated cable brackets, connector plugs, and flat
pin sleeves. Do not use insulating screw joints.
Use crimp pliers for connecting the cables with cable lugs, plugs or flat pin sleeves.
With cable connections to 31 (mass):
Screw the cable with cable lug and toothed lock washer to a vehicle-specific mass bolt
or screw it with a cable lug, self-tapping screw and toothed lock washer to the car's
bodywork.
Always ensure that the connection is properly earthed!
Warning! Due to risk of short-circuiting, always disconnect the negative pole of
the battery before starting with work on the electrical equipment of the vehicle.
In the case of vehicles with a supplementary battery, also disconnect this
negative pole.
Caution! When disconnecting the negative terminal of the battery, all volatile
memories of the comfort-electronics lose their stored data.
Depending on the vehicle's equipment, the following data may need to be
reprogrammed:
Radio-code · vehicle clock · time switch clock · onboard computer · seat position
Instructions on how to reset these can be found in the relevant operating instructions.
