I need to fix my o2 extension. Somehow it came unplugged, banged around on the ground and now both ends are gone (off the o2 and the extension), the other end of the extension is soldered in place and didnt use a very nice color scheme to my wireing (2 red and 2 black, go me). Anyone tell me what each wire for the fornt o2 does? Then i can kinda figure it out by looking at the other side also.

 

Go to the wiring diagram on Shoebox's website:

Even though its for a 95, the O2 connections/pinout are the same as the pre-cat sensors on your 96.
