2007 Peugeot 308 Lock Trigger

Yes.

Ok will let you know how it goes. Maybe it will work without connecting proper door trigger wires. Trigger wire on pke is fine when on +12v, when on ground pke unit is clicking, I guess proper wire would be ground when doors opened and otherwise +12v.dk

Yes that's the norm for 98% of vehicles.

It doesn't work. It does lock/unlock when locking. It only locks properly when you ground lock wire AFTER opening unlock wire. If ground is present before it than it does lock/unlock(in same second). dk

Ok I have managed to solve it. I connected unlock wire as on diagram above. I used a relay to switch steering light pke signal from + to minus and connected it to trigger lock wire. Now it is working flawlessly😀😀. Now I will continue on connecting steering lights. Can I use only one pke wire to trigger them all since my other is used as described above. The idea is to connect them(4 of them) through diode to positive pke trigger?dk

Yes, but relay it with 4 X 3 amp diodes (1N5404).

Can I use other diodes or must it be those?dk

You need 3 amp diodes for the indicators, 1 amp will blow 1N5404 is the most common, they are all the same price but 1N5401 up will do.

Also, how many relays doI need?dk

One. Unit's steering light (+) out put to relay 86 Ground (mass) to 85 12V+ constant 15 amps to 87 Output via 4 diodes from 30.
