i got a 2005 sti 02 sensor was wondering if it would be possible to use with my02 wrx motor swaped into my98 gc8 if so does anyone have a wiring diagram of the sensor to find which wires are which so i could splice it into my harness

Any particular reason you would want to go through all the trouble? Why not just get the correct sensor for your ECU?
