I guess the problem is this forum is mainly frequented by guys in the US of A where E46 318i was not an option. Having to rely on participants from England, Australia or South Africa for a useful response.
Umnitza may not even be able to answer for this reason, no experience with Angel Eye installs on 318i where that connector with the Red/White line/Yellow trace wire does not exist.
I am thinking of going behind the fuse box and picking up a trigger from the Radio fuse, F7, and secondary trigger from Interior Light Fuse, F49.
