I'm about to install an air/fuel gauge in my car and I need to know which wire on the O2 sensor I need to splice into.

Thanks in advance

On my car it was purple but I have 200sx. It will not be the black one.

if your car is n/a I would say ditch the gauge and get one thats more usefull. Just a cool gauge with lights......

Going DET in about a month!

By the way, I copied your gauge setup:D

Thanks for the idea!

hey man if you wanna save some dough and kill a few birds with one stone get the new apexi turbo timer 90 bux -i monitors:o2 sensor voltage(a/f can be displayed) displays a/f as rich or lean-shows battery voltage high/low(user definable) of course the timer and it would go oooooooh so nicely with uuumm maybe a s-afc and avc-r, i freakin love all of them.
