Electrical system for towing hitch
Important notes
Read the installation manual prior to starting work.
The electrical kit should only be installed by qualified personnel.
Caution – Disconnect the battery!
Danger of damage to the vehicle's electronic system. Data which are stored
electronically may get lost.
Read out the fault storage prior to starting work.
Use a closed-circuit current conservation unit if necessary.
Make sure prior to drilling that no objects such as cables, for example, are located behind the
covers.
Deburr any bare body parts, like bore holes, and seal them with the help of some rust inhibitor.
Note
During installation, special attention has to be paid to the following points:
•
Cables may not be pinched or damaged.
•
All sealing elements have to be installed properly.
•
The socket gasket has to be positioned on the insulating sleeve and not on the individual
wires.
•
Lay the cables such that they do not rub on the vehicle and are not bent.
•
Do not lay any cables near the exhaust system.
•
Install the controller such that it is protected against the intrusion of moisture. The cable
connection should always face downward.
When a trailer is used, the rear fog lamp of the traction vehicle is deactivated. In the case of
trailers without rear fog lamp, a rear fog lamp has to be retrofitted.
When a direction indicator lamp fails, also on the trailer, this is indicated by a higher flashing
frequency. No additional direction indicator check is necessary.
Use a corresponding adapter to adapt the system to a 7-pin trailer socket. The adapter is
available in specialist shops under the Westfalia part no. 300 100 320 113.
An electrical socket adapter may only be used in conjunction with a trailer. Remove the socket
adapter when the trailer is no longer used.
Correct trailer operation has to be checked using a trailer or a test instrument with load resistors.
