SR Wiring ??? - o2 Sensor cut, is this the plug?((pics))

[TurbLu]

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.
