headers and O2 sensor

[86GT]

I've heard of a harness that plugs into the o2 sensors and it extends the wires for you. But I'm told its rather expensive. The simplest and cheapest way is to splice longer wires into the existing o2 sensor wires (do this one at a time to avoid mixing up which one is which). Use good wire and make sure to wrap all your connections and tie them so they don't contact the exhaust. I've had that work for over 2 years now. Hope that helps.
