All the PIRs I’ve ever come across have four terminals (Usually a “chocolate block” screw type – these have a central barrel with a clamping screw at each end and are insulated by an all over plastic covering). They are incoming Live, incoming Neutral, incoming Earth and finally outgoing switched live via the PIR
The incoming mains wiring, which currently (Until next year) is Red – Live which should come via a switch located inside the building and giving isolation and complete control over the final load and PIR, and is connected to the PIRs Brown terminal. Black – Neutral to the PIRs Blue. Green/yellow (Or bare copper wire sleeved in G/Y tubing) – Earth to the PIRS Green/Yellow and the fourth wire is the PIRs live output or switched live (It becomes live when the PIR detects heat and turns itself on) This is connected to the final lamps live terminal. - Hence four terminals/wires.
I cannot really understand why you would have four incoming wires to the PIR, unless the PIR is remote from the light fitting, then normally the Yellow wire would act as the PIR switched live and this goes to the live terminal of the final lamp. If so, it should be sleeved RED.
I would advise you to check with the PIRs instruction leaflet and if you’re still not sure employ an electrician.

It is possible to buy a wider range external PIR. However you may need a qualified spark to fit it for you. May I suggest an external lighting system from a company called GJD. With this system you can have multiple PIRs and Halogens/Lights.

Can't draw it very well in text but something like...
|--Timer---|----- transformer --- lamps ---- Neutral
Other connections may be necessary depending on the details of the equipment but that's the basic idea.
...of course Building Regs these days don't allow you to install 12V lights on your own (except as part of a prewired set and only then in certain places - eg not outdoors or in a kitchen/bathroom).

The PIR sensor is shown in the diagram as being inside, obviously this has to be outside.

You need to find a live cable you can tap off - and that's going to be up at the light pendent, not at the switch.
