Hi Overrider,
This is my first post here, but I've been lurking for a good few months now as can be seen from my registration date. I can't resist helping a fellow vancouverite out however Here's some information I got from someone in another forum about how to hook up DTR lights for the altima. I didn't make this information myself, nor have I ever done it so I can't really help, but it should give you a good idea about how it's done. It's a PDF file so you can get it from:

I think it's actually for a 07 altima, but it should be almost the same process, I'd imagine.
Btw, you did the exact same thing I want to do. I'm in Vancouver too, and looking to go down to Washington to get a 3.5SE AC (thanks to the huge redflagdeals thread on the subject). Do you mind if I ask you around how much it cost you and whether the Vancouver dealerships will honour the warranty?
I *really really* want this car and have been amassing information about it and things I want to get done to it (Add Avic-D3, rearview cam, sub, tints/headlight overlays, rims/tires) when I do get it!
