I personally would try to keep it OBD-2, since you're not modding it for racing or anything... I really wouldn't bother trying to swap the wiring harnesses and such, since in my experience, it's a huge PITA for nothing when you have another option that's just as good.
You also get the advantage of using a
scangauge, and OBD-2a will basically tell you when you fart in the wrong direction... you'll get a code for it.
Learn to read/clear those codes, you'll have a better chance of diagnosing/fixing your car without taking it to a shop who will rape you on service rates/hourly beer break rates.

I'd like to think that people might open their eyes at some point... instead, I find it more and more likely that I'll just close mine.
