Mr. Prelude

Hello!
I have a 1990 prelude SI. Small problem, pulling the engine out I accidentally pulled on the o2 sensor and pulled the pins out of the plug, from the harness side.
Basically, I got 4 wires from my harness. A black one, a green, a white, and a yellow(maybe orange).
You can see my problem here. I have no idea how they mate up to my o2 sensor. My o2 is some NGK with 2 black wires, a white, and a green.
Any help of how they mate up would be nice, I already drew up a chart of all 24 possible trial and error combinations the wires can mate up. But that sounds tedious!
Thanks!

Did you rip off the whole plug or just pull the pins out(pins still connected to the wire?)? I have pulled pins out of their plugs and I am usually able to put them back in successfully.

You can try a few different things:
Get out your trusty Prelude repair manual and find the wiring diagram with the O2 sensor wiring configuration. Find (online) the different wire functions for the NGK.
If you cannot repair the plug, you may have to solder and heat-shrink the wires directly (hardwiring to the harness). This would involve cutting your plug off the O2 sensor.
Say you have only one wire pulled from the plug, you could put a male and a female connector on just the loose wire and it's mate and plug in the rest.

Hopes this helps you.
