Ok, so I bought this air/fuel ratio guage for the ole zetec and I'm looking at the instructions and a few questions are popping into my head. Where is the signal wire to the O2 sensor in the harness? obviously the guage wire isn't long enough to run allllll the way to the sensor itself, nor is it intended to.. so does anyone know where to hook it up to in the harness wiring?? also what would be a good 12V wire to tap that is run through the ignition so it only works when the car is on?? muchos gracias!!
