Fuel line

A/F gauge gets its input from the o2 sensor. The Autometer gauge has 3 or 4 wires coming from it (depends on model). One wire is the power (red), one is ground (black), one if for the lights (optional. dont know the color of this wire), and the other is for the o2 sensor (purple).

Tap the purple wire to the o2 sensor wire thats connected to the ecu (look at the factory service manual for this wire), ground the gauge, connect the power. Turn on your car and let the o2 sensor warm up and now you can see a/f readings on the gauge.
