Fitting an PIR system with a 3 core & Earth

[Mush247]

I bought a Homebase 60W PIR lightening and I'm having problems getting it to work. I removed my existing PIR light that wasn't working and replaced it with this new one. The current set up is a double switch with a 3 core & Earth (blue,yellow and Green,Live Brown amd yellow) coming out the external wall. The new PIR have Neutral (blue)/Earth (yellow and Green) and Live Brown), the question is where do I put the extra Yellow wire coming from the switch?

As you can see I don't know too much about these things.

Thanks

Sorry if it's a stupid question, maybe it's like asking a Brain surgeon where do I start cutting.

I wonder if it is similar to //www.diynot.com/forums/viewtopic.php?t=57688&highlight=pir ?

(except that standard cable colours changed a year or so ago)

They used to be red, yellow and blue (plus earth, bare with green& yellow sleeving)
