Hey people, quick question:

Just got an Autometer Air/Fuel ratio gauge used, Number 4375, and it didn't come with any instructions.

I already know where the red and black wire goes to, and I know that you hook up the purple wire to one of the wires on the O2 sensor, but which wire is it?

Thanks

Also, this is for an OBD1 O2 sensor.

Thanks

 

the white wire on the o2 sensor, red goes to ignition(power) black is ground

 

Here's what you do. Sell the gauge for $40. Get some x-mas lights and install in car. Now your $35 dollars ahead. :D But Kp is correct, white wire is sensor input.

 

its red=12+volts black=ground purple=signal splice the signal wire up with the white/creme colored wired of the blue 32pin connector that goes to the ecu
