Hi,
I know wiring diagrams not free in the net and need to have account for that.
I need badly schematic of blind spot alert of Insignia 2014.
I have a check procedure for my error but don't have a wiring.
Can attach procedure for testing but he is partial usable because don't have wiring codes and connectors.
That i thing in astra J system will be the same.My error are U18A6.
If anyone can help will be good.
Regards
