Mark the motor cables for both motor units using the cable markers (25). The cables for the left and the right
motor should have the same length. Avoid any loops.
Remember to leave a small amount of slack cable near the motors to allow for their movement when the drive
rollers are engaged.
Route the motor cables along the underside of the caravan floor, inside the supplied convoluted trunking (11)
(this will protect the electrical cables against sharp edges and dirt) and through the drilled hole.
Secure the cable trunking (11) to the chassis or under body of the caravan by using the P-Clips (20) and screws
(19).
Once the motor cables are through the drilled hole next to the control unit (4), cut the cables, ensuring that
they are same length. Remove approx. 5mm of the insulation from the ends. Fix the spade connectors (24) by
using crimping pliers. A secure and good quality connection on each cable is essential.
Attach the connectors to the terminals on the control unit (see wiring diagram Fig. 12).
The cables for the automatic engaging system are linked to the control box through a connector (Fig. 12F).
Disconnect the connector and connect the cables according to the diagram. Afterwards the connector needs to
be connected to the control box again. A safe and good quality connection on each cable is again essential.
Find a suitable place for the battery power isolation switch (29) which includes an external holder with hinged
cover. Important: The switch must be mounted onto the exterior body of the caravan and be easily accessible
from the outside of the caravan in case of any emergency. The switch must be mounted close to the location of
the battery in order to keep the length of the battery cables to a minimum.
The electronic connections of the battery power isolation switch (29) must be covered by the supplied rubber
isolation shells (31).
Route the positive (+) power cable from the battery to the battery power isolation switch (29) and than further
to the control unit (4).
Route the negative (-) power cable directly to the control unit (4).
No cables may be routed over the control unit!
Again it is recommended to use the supplied trunking (11) to protect the cables against sharp edges. Attach the
trunking with P-clips (20) and P-clip screws (19).
Cut the cables to an appropriate length and remove approx. 5mm of the insulation from the ends. Fix the spade
connectors by using crimping pliers. A secure and good quality connection on each cable is essential.
Connect the battery cables to the existing battery terminals (red = positive, black = negative). Two types of
battery terminal connector (22 & 23) are provided for use as appropriate.
Caution! Make sure that you do not reverse the Positive (+) and Negative (-) connections.
Incorrect connection (reverse polarity) will result in damage to the control unit.
Connect the battery cables (14 & 15) to the control unit (4).
Seal the 25mm hole in vehicle under body using plastic body sealant.
Next you can connect the emergency cable for the automatic disengaging system. If you forget to get the
power rollers of the tyre before you start to drive, the caravan manoeuvring system or caravan can get
significant damage. The emergency cable ensures that (if installed properly!) the rollers automatically come off
the tyres, when the caravan is connected on the 12v power supply of the car (via 7 or 13 pin connector).
Connect the cable (Fig. 12E), that already is connected on the control unit, to the +12V power supply that is
direct connected with the constant power source (+12V) of the car (via 7 or 13 pin connector) and not in
direct connection is with the caravan battery! Use the supplied cable (27) which is already provided with a
connector, that can be connected on the cable of the control box. (Fig.12E). You can find this constant power
source in the 12V central distribution box of your caravan (if necessary measure again with a multimeter)
If necessary you also need to connect the ground (-) of the existing caravan system to the minus of the control
box (when the caravan battery is also used for lighting/water pump of the caravan it is not necessary).
If you need any help finding the constant power source of the car (in your caravan) please contact the
manufacturer or supplier of your caravan for the wiring diagram.
NOTE: This constant power source (+12V) CANNOT be in direct connection with the caravan
battery! Check this very carefully, otherwise the caravan manoeuvring system will not work!
You can test this by disconnecting the connector from the car so the constant +12V voltage
drops. By connecting the connector on the car again, the +12V voltage will be restored. If
