SR Wiring ??? - o2 Sensor cut, is this the plug?((pics)) - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

Ok guys... Im at the last of my Sr swap wiring details. I need to extend my o2 sensor but its cut at the o2 sensor (about a foot away from it). Im pretty sure this plug (pictured below)is the plug. I dont have the end that plugs into it for the o2 sensor. Should I cut the plug off and use quick-disconnect connectors? Also which wire connects to which plug?

Red: (brown Im assuming)
Black: (black I'm assuming)
White: (white Im assuming)

Am I correct here? Or am I totally wrong and this isnt even my o2 sensor wiring? The pics are down on frsports wiring diagram so this is making it harder for me to figure out.

bump for help on this topic - could someone go outside and check for me...

What's outside?

Do you have a new O2 sensor? Because that would tell you right away, but I'm feeling nice. Yes, that's the O2 plug, engine harness side. And I don't know why you're extending it, if anything it needs to be shortened since it's about six inches too long. Unless you're one of those 'stuff it all behind the engine and make it look like shit' kind of guys.

lol took the words right out of my... well, wherever words come out on the forums.

No reason to lengthen, but yeah you've got the right wires, I'm not sure about the pinout though - I just remember it's counterintuitive.

I had to lengthen mine slightly, but I prefer to reroute the O2 sensor wires as far away from the heat source as possible. This is not necessary.

Search for my threads on O2 sensors. You will see the wire colours. All 3-wire heated narrowband O2 sensors are very similar. They consist of the signal wire in the middle, and non-polarity 12V (+) and (-) wires on the outside.
