See the diagram/photo and discussion in this thread a few posts back.

Left - Brown = Live in/supply.
Centre - Blue = detector/cell terminal one.
Right - Red = Switched live/load.

Other detector/cell wire goes to neutral and is combined with the load neutral.


For the P42E, centre pin is connected to neutral and the detector is connected to the 2 small sockets on the underside of the relay.

The ballast should be wired one terminal to supply and the other to the lamp. 2nd terminal of lamp goes to neutral. Ignitor is connected across the lamp - in other words, one terminal to neutral, other to "lamp live".

If you search the lamp and gear section of the forum you will find loads of posts and topics on how to wire up control gear.
