o2 Wires.

[lil.honda.man]

I got two black, one green, and one white on the car and the o2 sensor has one gray, one black, and two whites. On the wiring harness though its a orange, yellow, a green, and some other color. What goes to what?

Check the little booklet that comes with it. It;ll tell you which one is what.

Probably help if you broke it down a little better and explained what you are trying to do. O2 sensor harnesses are fairly standardized. I know on Bosch sensors the black is signal +, gray is signal ground, and the white wires are heater + and heater -.

yes ther white heater wires dont matter which polarity they are, you can get them mixed up and its fine, i actually JUST got done doing this today on my also 93 civic 4dr, the one heater wire goes to the orange/black wire on the ecu, the other has to be spliced into that connecter that goes nowhere with all the yellow/black wires, the gray wire goes to a ground, the black wire goes to the o2 signal wire, which of your going from 1 wire to 4 wire i just used the stock white wire
