Laguna II Airbag Ecu Pinout

hi all i have looked everywhere for an airbag ecu pinout for my 2005 laguna ii but cant find one,

any help greatly appreciated :)



reason for needing this is i have check airbag on the display, plugged into a scanner and it came up with n/s curtain airbag fault, cleared codes but came back in a few seconds



im a car breaker and deal with mainly renaults and had a good laguna ii in with no airbag issues so changed the airbag but the fault still remained... so did a little digging and found a previous owner for some stupid reason had the plastics off at the side of the back seat and cut 4 wired 2 blue 2 brown then rejoined.. maybe frayed wiring or something i dont know... cant be sure they didnt mix them up so hence why i need a wiring diagram



thanks for looking :)
