I need to know which wire is the signal wire for the oxygen sensors. I have a choice between red, black, violet, and off white. I think the red and black are + and - for the heater, and the other two are high and low signal wires. I need to know which one is the high signal wire, or which one to tap into for and A/F ratio gauge. I'm in desperate need of some help. Thanks
