Ok, so i already tried searching for a definite answer to this problem and came up empty handed.

I have a defi afr gauge and i am having trouble with the signal wire.Im wiring it in to the ecu. From what im reading, this wire is the white wire on the farthest right harness. the pin is d7 i think. i tapped into that wire. My gauge illuminates fine, does the startup celebration, but doesnt read the air fuel ratio. Would i have better luck running the signal wire to the o2 sensor and if so what wire do i tap into. Thanks
