these are the 2 connectors
white connector comes from dash(corsa) and has a black with white and a brown with white wire
the black connector comes from astra loom
the others all just plug in no problem

is the car second hand, it could be some sort of old car alarm or soemthing to that nature

looks like a relay connection.Understand that the wiring loom comes from the factory standard with a lot of connections wich are not used on some of the cars for electric windows,aircon ect...go digging around and ul find more open connections like that.Is everything in the car working ok?
