Your 4 wire o2 sensor has two black and a green wire? 2+1=4
Anyway, the purple wire hooks to the o2 sensor, I'm guessing its the green wire, you can check it by hooking up a voltmeter and see if you get between 0-1 volts while the car is warmed up.

Then hook up the black to a ground and the red to an acc wire. (wire that comes on with the ignition).

one of the wires on the a/f guage must be light it up at night

Tap into your ECU with the purple wire and leave the 02 sensor alone.
