o2 sensor wires

hey guys, i have a problem with my o2 sensor wires. if any of you have ever installed an air/fuel gauge, you may be able to help lol...

obviously i bought one, and am having trouble finding the 02 sender wire...i found the o2 sensor, sticking out of the downpipe, and there are 4 wires coming out, 2 black, 1 bue, and one white. anyone know which is the sender wire??? thanks!!!

have a look at my install thread

thanks that was a big help, and i figured out why my gauge wont work...

i researched enough to know that it was either of the black wires, so i figured, what the hell i tried BOTH of the other wires...

well the gauge would go back and forth....back and forth...lol

looking at your install, i realized that i have a wideband sensor....not a wideband gauge, therefore not a good combination lol...

thanks a lot buddy, very helpful pictures, and nice talon!
