Hi everyone this is my first time posting. I have a 99 cobra I am trying to data log my aem wide band on my SCT x3/fs3? Not exactly sure. I have a fire wire and wired the 5v out put to the orange wire and the blue to my chassis ground but when I data log on the SCT it reads aem 10.0 and does not change. My gauge reads fine. Do I need to wire the white wire to power and black to ground also? Or am I doing something wrong? Thanks for the help
