Where is the wiring harness located that hooks into the front o2 sensor wiring? I had new exhaust put on my 96 talon tsi and I cannot find the wiring again. If anybody could help me out I would appreciate it. thanks

 

the sensor that is near the cat goes up through tthe floor and then under the seat

 

Are you talking on the exhaust at CAT or on the O2 housing itself? cause yes, the sensor at the CAT is pretty much adjacent to the bunge. but the one on the O2 housing is on the left side of your engine bay. Looking at your car, left side of your valve cover, about 4 inches left and down in a hole. the wiring runs from the housing back across your exhaust mani, being held by the clips on the heat sheild. across that, down and around your turbo coolant lines and up toward your windshield about 10 inches.

I lost mine for about an hour too, don't feel bad. you wouldn't even believe how pissed I was

 

Found it. Thanks guys. Now that I see where it is I feel dumb. Kind of in the open. Thanks again
