air/fuel ratio meter??

anybody know how to install an air/fuel ratio meter for 95 nissan maxima??
i want some detailed information before i get them..

thanks

One wire goes to the ground, one goes to the ignition hot wire, and the other one goes to the oxygen sensor input at the ECU. You only need one if your going NOS :D or forced induction. It is a bit of a pain to install, and I think I'm going to pay someone to do mine. Good luck. :sun:

just a note, i spoke to autometer about the lack of accuracy from my a/f meter. he told me the a/f gauge does not work on nissans. i ask him why no warnings about this and he did not know. however, when i installed my s-afc and adjusted the fuel %, the gauge seamed to be very accurate.

I ended up installing mine myself without any problems. It serves the purpose for the NOS, it does tell you at WOT if you are lean or not, I don't think that guy at autometer knows what he's talking about, because a lot of people are using them on there Max's, but oh well. :D
