Ok, so I charged the battery and went through the procedure to program the starter again. This time it started up. The only thing that seems to work is the brake switch. The horn doesn't honk and the door doesn't lock. I thought I followed the diagram properly though. I guess my question is if anyone has an idea exactly which wires I need to tap into to make these work?
BTW, I skipped the parking lights, since I didn't feeling like dealing with that. Looks like that was a good idea on my part.
