well you guys know from my last post I don't have a FSM yet, so could you help me out with two things?

AFM pinout - need to find intake air temp wire... and is it a thermistor or what?

And how do I get trouble codes and where might I find a list? I know you guys are full of links... Help a brother out who's trying to make a customizable engine control sys for his woman's maxima... solder solder, cut cut, solder solder, cut cut...
