HELP: Wiring up my new o2 sensor, After the first was ripped out!

[Runner4liife]

:sadwave: Some a**hole cut my cataylic converter off including my front oxygen sensor, so i got a new cat welded back up there and installed a new o2 sensor (air/fuel sensor) and i was just gonna cut the plug off the new o2 and just wire it to the wiring harness where it was ripped out. does anyone have any advice or experience rewiring an o2 sensor to the wiring harness? ill add some pictures to help.
The end of the wiring harness

Better view of the wire colors, kinda blurry :/
a Brown, white/blue strip, off-white, pink/blue strip.

new o2 sensor wire colors:

pleaseeeee help, thank you.

easiest solution would be to find a salvage yard and see if they will sell you the plug with a bit of a pig tale you could solder in to place. Other option is to grab a service manual and check the pin out of the stock plug and just match it up with the sensor. Then either solder it direct or go to the pick a part and grab matching sides of a 4 pin plug. (unless you have access to a crimp tool and connectors) The sensor itself you should be able to get the pin out from the manufacturer.

Guessing its an NGK (NTK) piece: NGK Spark Plugs USA

My 3rd gen is a '99, 5 speed and a California model. As such my front 'o2 sensor' is actually an air/fuel sensor. It has a different part number than an o2 sensor. It is my understanding at at least the '99 CA models have this as a buddy with a non-CA '00 has an o2 sensor where I have the A/F sensor.
You might want to make sure you have the correct part. I was also told you can't splice in a new sensor becuase they work on resistance. If the wires or connections aren't jist right it won't read correctly. My sensor had a plug at the end of it's wires. They plug was at a near impossible location on the top of the transmission. It took 2 hours, a mirror amd a seal pick to undo the old plug. YMMV.

The sensor should be pretty easy to hookup since it just has 2 wires for the power and ground to the heater and one for the output. If it has 4 wires it might have a second ground that goes along with the output. The 2 white wires are probably grounds. You'll probably need to check the wiring diagram to find which wire colors are for +12, ground and the input but if you can find the ground and +12 wires for the heater with a meter then the one that's left is the input. On the sensor you should be able to measure somewhere between 6-8 ohms between two of the wires which go to the heater. The other one left over is the output. After it's all hooked up connect the voltmeter to the output lead and check after the engine is warmed up that you get between 0.1-0.9 or about 0.5 volts average to make sure it's working properly.
