Since I've turned this into my own build thread now... more (arguably pointless) mods!
Red third brake light. Didn't like the contrast of the white one against the black paint, looked especially out of place once I went to ambers. Red gives it a more "aggressive" look in person, as much as changing the color of a lens can anyways, and works to also sort of hide the light which isn't a bad thing. 10 minutes to replace... very easy job
Aux-in, put it in the glovebox. Have it wired currently so the wire goes back through the console and pops out from under the e-brake boot - having the wire just come out of the center consle made it not close evenly but putting it off of the glovebox seemed stupid to me. My other cars have the aux-in in the center console so figured why not...
Also got a used seat module to replace the one in the car, original problem was seat position memory wasn't working and steering wheel wouldn't move. Nice to have that working again, thought it isn't raising/lowering when I enter the car. Maybe indicative that the used part I bought is on the way out... either way it works now so I'll enjoy it!
Ribbon cable to fix pixels showed up too... little afraid to tackle the job... but I'll get around to it soon
