PSA s2000 pm2 cemo / connector 48 V MR pinout diagram

[loook_bestsolution23]

Good day for all
I have issue with wiring of 407 1.8 16v
I found an other wiring group but the plug connector going to ecu is small not 48 V MR
The ecu is Sagem s2000 pm2
My question is I can remove the wires from the small plug and solder them in the other plug old one according to same colours?

I would think that it is risky, especially as PSA do not keep the same colours, even on the same vehicle. If you have the VIN number of the donor vehicle, maybe the wiring diagrams can be compared.

You can actually remove the wires complete with terminals from those connectors.
