air fuel ratio gauge
 

my gauge just reads rich all the time. now my car was having some idle issues i had early taking everything off the ecu harness and put it back to stock.

now the gauge doesnt work, i assumed that it was just spliced into the o2 sensor. but i guess its not.

i cant seem to find any sites or threads with this solution. does anyone know what wire i have to splice into off the harness?

thanks.

Always connect A/F gauges at the ECU. Stay away from the O2 sensor.

do NOT depend on that for tuning your turbo car! get a wideband!
