af gauge install autometer
--------------------------------------------------------------------------------
I am trying to hook up my purple wire to the o2 sensor wire from ecu instead of the o2 sensor in engine bay, but there are two white wires and both seems to be same fatness. Which is the one I should be tapping to?? Got everything hooked up except for the purple wire. Please help..thanks..

its best if you connect it about 3-4 inches from actual sensor be a little more accrate that way

your pcm bases your short term fuel trim values off of the o2 reading the farther away the sensor is from the signal wire, you might have a little delay in your gauge reading. the o2 sends values from .1-.9v to the pcm telling rich or lean. your a/f gage is just a little volt reference that goes from .1-.9v . .1 being lean and .9 being rich
