First of alll, it is a hatchback. I am trying to install the EFIE (short for electronic fuel injection enhancer) into the highside wire of the 02 sensor. Some oxygen sensors have wires labeled highside and lowside. The manual will tell you. Which is the highside signal wire, but I do not have a manual. The correct oxygen sensor signal wire will have no electrical connection (continuity) to: the vehichles ground(negative) or the vechicle exhaust pipe, and any other wire coming from the oxygen sensor. I checked continuity from the sensor and everything has continuity. Thats why I will give you the color and number of wires: 2white, 1 black, and 1 light gray. Those are coming from the 02 sensor. I have different color wires that it is plugging into. 1 is pink & bllue, 1 brown, 1 black & blue and 1 white.
