Electrical Installation
Whilst the adhesive is curing prepare the electrical connections for the Control Box. The Control Box
requires a permanent 12V supply and a secondary 12V supply that provides power when the engine of the
vehicle is running. Note: the brake light circuit is not suitable.
It is recommended to create a new circuit direct to the battery using a minimum cable cross sectional area
of 2.5mm and an inline fuse of 5A. Do not connect to existing circuits that supply high power devices such
as water pumps, air conditioning units or sources of interference such as electric igniters for gas stoves.
Route cables carefully avoiding areas of excessive heat such as exhaust systems and any moving parts in
the engine compartment or drive shafts.
Power Cable colours:
Black
Green
Red
Join Power Cable to new circuit using a
robust connection method such as...
• Crimp connectors
• Screw terminal connector block
• Snap fit automotive tap connectors
Caravans
Power can be taken directly from the leisure battery on the caravan. The ignition cable should be connected to
the ignition key circuit which can be traced using the charts below. The caravan will either be fitted with the
13 Pin Euro Connector or have two 7/8 Pin connectors.
