air/fuel ratio hook up
 

i just bought an air/fuel ratio gauge from autometer sport comp
i found the o2 sensor wire
its a pr4 ecu
i have the 92 civic harness
the color of the wire is orange/blue
the voltage coming out of the wire was like 13.5V
is that right?
and the voltage went up as i reved the engine up.....

hmmm....is this the right wire to tap my purple wire to???

i tried !
found nothing that helped....

i already tried hooking up the gauge to the o2 wire....
it just shows the extreme rich...(green)
and stays there....the voltage it is recieving is 13.5 v.....
that is way off....i should be getting between 0-1v
what the hell is going on?

well I just searched and I came back with

purple from gauge - white or green wire from O2 sensor
red from gauge - Switched Power source (preferably not spilced off something else)
Black from gauge - clean good chassis ground

so try the white wire and if that, dont work either your gauge or o2 is messed
