Bought an A/F guage off ebay

box had been opened, which really is ok with me.

Whats not ok is that the wiring diagram is for a temp sensor....

ill get pics tomorrow and hopefully we can get this thing figured out....

black wire goes to ground, other wire goes to sensor. easy peasy.

There's no wire for a light?

mine doesn't have one. the only lights are the blinky display. which is not to say that the one in question couldn't...

Yeah, but the blinky display gets it's power from? The O2 sensor only puts out 1 volt and a few milliamps, not enough to power the LEDs on the blinky display. That's the light I was talking about, unless your blinky display is dark or something. :wink:
