It's been a long time since I did my AEs (I think I may have even gotten frustrated and taken it to a local stereo shop for them to do), but from what I recall: the power line needs to be connected to the power terminal on the firewall, run it through a relay to the corona rings, trigger wire can be connect in a number of ways depending on how you want to actually trigger them. I only wanted them on with parking lights and headlights, so I had it wired to the parking light terminal on the LCM. I suggest taking it to a shop, IIRC it wasn't but like $75 to have them install.
