Central locking relay, positive or negative

[laser55]

Does anyone know if the italamec centralina bloccaporte fitted originally to my Chimaera 4.0 1994 has a positive or negative locking pulse? I am considering fitting a meta 20/12 (which is positive pulse)or a meta 20/11 relay negative pulse, I will be doing something else to activate / get round the immobiliser.
