""It is easy to figure out the four wires, all you need to know is use multi-meter to identify the ground, and the two same color wires are for heater, and the rest wire is for signal! Use the above method you even do not need to care what color the wire is. I solder the sensor wire with the old wire, because I do not trust the clamp."" posted by: mountainman on September 1, 2014
