are there any wires coming out the back? there should be a wire for 12v, one wire to go to the signal return for the 02 sensor. you make this connection at the computer. there should also be a ground. you can get another gauge and m ount them in a gauge pod if u dont have one already.
Nope, I don't have wideband and yes, I am aware that if you dont then its just a light show, but I am getting the gauge for free so the light show is fine with me.
