Need a little help, can I add a second PIR with a single core line in (live)

Will this work?

Welcome to the forum mate.
Theoretically, your diagram will work.
What cable you thinking of using?
So you show the outputs from the PIRs are linked, so all the LED lights will come on if either PIR is activated. Is this what you are after?

Thanks for the welcome.

The PIRs are linked so yes that’s exactly what’s needed, and I can use 1 core of a 1.5 x 3 core armoured cable, I known this is a bit over kill but it will run part outside and part underground.

I would send a three core around from the left PIR to the right one picking up the lights and use the spare as live feed and defo ditch the double connection at the CU...
