An update on the questions I asked about:

I've successfully converted my side markers to side repeaters (I'm aware there are both dual purpose LED side markers and wiring harnesses to make a single bulb work as both, but I was going for non-US OEM functionality). Here's the video that I used to find which wires to tap on the '17:

Second, on the independent fog question, it looks like it uses a relay just like my RX-8 did and I just need to make the parking lights (or tail lights) trigger the relay instead of the headlights. The BRZ wiring diagram that is on this site shows what that would look like (must be a non-US wiring diagram, because again, that's how it works outside of the US):

http://www.ft86club.com/files/BRZwiringi.pdf (see pages 195-196. See how the fog relay is tied to the tail fuse. I'm not an electrician, but I believe I'm reading that correctly.) The relay looks like it might live inside the main body ECU though, so maybe I won't be able to gain access to it.

I'm planning on digging in and trying this mod this weekend. I'll post back if I have any luck.

Still hunting for solutions for the DRLs, but if I can run with just fogs and DRLs I'll be happy and don't necessarily need them to stay bright with headlights.
