Caution : Disconnect power from the control board before beginning any wiring.
Each existing wire must be left connected and if the SOLO KIT connection uses the same contact as other wires, the new wires must be added to those already present in the same contact.
NB
If on the Cardin receiver the original cables are connected to channel 2, therefore connectors 2 and 3, then the KIT must be connected to those and not to connectors 5 and 6 as shown in the diagram.
On the KIT side the connection remains unchanged.
