Fitting new PIR

[Steve128H]

I want to fit a new PIR in the bedroom the old one is old and has gone discoloured.
The wiring colour code does not tie in with the installation guide
The old PIR is wired as figure two
The new PIR is as figure one

I am uncertain which colour wire to fix to the tamper and alarm contacts.
There is not many combinations I am just concerned that if I wire incorrectly it may cause damage
If any one could advise at all please
I will call 0v contact one through to contact 6

The terminal names seem to match up....
Green to tamper and blue to alarm.
What exactly is the confusion?

Edit: I note that the power terminals are reversed

The alarm and tamper wires shouldn't matter which way they are connected. They're simple switches.

So you can put the blue wire in either contact 3 or 4 (as long as the blue/white wire goes in the other one). The green and the green/white go into terminals 5 and 6.

For the power the old one has + and - but the new one says 12v (+) and 0v (-). Slightly different labels but they mean the same thing. They do need to be done right, as endecopt says they're reversed in the new one so brown to 2 and brown/white to 1.
