Angry Need Help with Air/Fuel install

Hey ppl does anyone know a way to to install the Air-Fuel pod in the Rex? I have tap it into the 02 sensor and i'm getting a solid green light.!~Aparently our sensor that we have in our 02 WRX is a 0-5vDC which feeds the gauge more voltage than it can handle and it stay on solid green and telling me thats its running rich. Does anyone know how to convert the voltage to a 0-1vDC so its not giving so much power to the guages so i can get this guage to work.. Please Help Thank you!!!

IMHO you need a wideband setup for it to be of any use. Both wideband sensor and display.

The stock sensor is no good.

This is about the cheapest around :-

Yep - front O2 is Wideband and the rear O2 after the cat is useless. You would need a WBO2 that provides narrowband output for the guage, and most would say that narrowband A/F guage is a filler

Your best bet is the link posted above. Your narrowband guage is useless to do any real measurements with, so you need the sensor and the display.
