ok, i ran my sensor wire (fromt the autoemeter a/f gauge) behind my dash, and i need to know of any wires that i can splice into the car to get the a/f reading. i know there's a wire on the ECU, but i am unclear to which one, does anyone know exactly which wires u can splice, that are inside the car?
