ok I know this has been asked about 1000 times!! Everytime I do a search all I find is a dead like or a link to something I don't wanna see.

Ok so here is the question!!

Where can I find a wiring diagram for a 90 CRX Si and a b16a1? Its got stage 3 cams in it and it barely idles(yes i knew this when I installed it. i also want to know if going to OBDI would be worth it and what computer I would need to do it?
