Floodlight PIR has red blue and black wires

[ban-all-sheds]

cant see any that can be used to replace an existing PIR that's part of a floodlight. They all seem to be stand alone.

I took a PIR sensor from an old halogen floodlight and fitted it to another of the same wattage.

So what part of that does not make it now a standalone PIR?

ban-all-sheds: I'm not sure how any of your questions helps with my original wiring query where I had hoped to draw on the vast wealth of expertise of the kind people who try and assist others with less knowledge, but here goes. You'll see from my original photo that the PIR is physically attached to the light and replaced a faulty but similar style PIR (with different wire colours). The replacement PIR came from a similar 'integrated' light, for example, https://www.ukelectricalsupplies.com/Timeguard-400w-Black-PIR-Halogen-Floodlight.htm. I could be wrong, but from what I can see none of the Steinel PIRs are remotely physically similar to the PIR I have and therefore seem not to be designed as replacements for the type of light I have as they cant physically be attached in the same way. They seem to be designed to be mounted somewhere separate from the light and then wired to the light.
