O2 Signal Wire
Hi, i'm trying to hook up an air/fuel ratio gauge i just bought...it says to tap into the O2 signal wire...There are 4 wires coming out of the O2 sensor, 2 black (grounds i'm assuming), 1 white, and one green. I drive a 1998 Civic Dx with a D16Y7 motor in it...can someone please tell me what wire is the O2 signal wire...If i am correct there is the O2 Signal Wire, O2 Signal Ground, Heater element ground, and Heater Element Power...
