need help with my air fule ratio gauge!!! does anyone know if it can be used on a 02 wrx if so what wire do i hook it up to?

have you done any wiring on the ecu before? you need a power source to splice into (a hot wire, 12v, and a ground) and the gauge reads off of the oxygen sensor(o2 sensor)......um here's a link to a wiring diagram for the computer, well the link wont work just type it in, and if you haven't done any wiring find a shop or something because its easy to mess things up
