First off i have a 94 mustang gt, and i got a autometer air fuel ratio gaue. It says to splice into the sensor signal wire. My question is which one out of the 4 is the signal wire. The colors of the wires are red, black, gray&yellow, and gray. Which is the signal, Thanks in advance guys
First of all, where are you actually trying to splice at? Not under the car right? You can splice in right by the computer. I'm not at home to look up the wire color but I'm sure someone else will chime in.
