Wiring an A/F gauge
 

Where do you guys run the wire to? the sensor or a wire into the ecu? someone told me if you wire it into the sensor it could disrupt the voltage. I have a 4 wire sensor too, so i assume it would be the green wire?

OBD-1 = D14 at ECU......but wire to the ECU........

The AF gauge is nothing more than a fancy voltage gauge with purdy leds.

I still use mine, even for minor NA tuning, but I also read the plugs too!
