An electrical connection box for use in a vehicle, e.g. a car, has a junction box and a circuit addition box removably mounted on the junction box and having a connector engaging portion for engagement in use by a connector of an external circuit. The circuit addition box has bus bars connecting circuit components of the junction box to the connector engaging portion to provide electrical connection to the external circuit. To achieve a compact arrangement, avoiding the need to adapt the junction box, the circuit addition box is removably mounted on a relay housing of the junction box adapted to receive a relay, the relay housing having electrical terminals engaged by the bus bars of the circuit addition box.
