Trailer with 7-pin connector
General notes
You can make a connection to the 13-pin socket on the ball coupling using an adapter or, if necessary, an adapter cable. Both can be obtained in a qualified specialist workshop.
Installing the adapter
Make sure that there is enough slack in the cable for cornering so that the cable cannot become detached.
► Open the socket cover.
► Insert the connector with lug 1 into groove 2 on the socket and turn the connector clockwise to the stop.
► Make the cover engage.
► If you are using an adapter cable, secure the cable to the trailer with cable ties.
When the socket is connected, the ultrasonic backing up aid is deactivated.
