Yeah, I'm not quite sure where to add this either because the parts you're talking about are so different. But anyway, HIDs can definitely be added, the pedals too. As far as the cruise control goes, I don't think you can. I don't think the Base ECU can work with it, but I could be wrong. I've never really looked into it myself because I want to do the opposite of you, take the cruise control OUT of my Enthusiast
