Hey guys was wondering if anyone can help me out I looking for some o2 sensor help I have a 96 chevy 2500 2wd pickup I picked up real cheap the truck was in overall good condition but it had no exhaust system so I Installed a new exhaust but unfortunately whoever cut out the old exhaust went a little crazy and ended up cutting one of the o2 sensors wiring harnesses off the truck after the connector so now I just have 4 wires hanging there so my question is how do I figure out what wire goes to what wire when hooking up the new sensor any help would be greatly appreciated thanks
