vito 447 wiring issue

[ziggytwizzer]

hi I have a 2015 Vito with srs airbag light on, under the twin passenger seat I've found that someone has cut the block connector off connecting the centre seat belt and buckle to the van, my question is does anyone know which color wires connect to each other or have a wiring diagram for this section I've attached a pic of the wires, would be most grateful for some help, ps iam trying to find the correct block connector
