Okay, for two F*CKING hours now my 02 sensor on my 89 TII has been unplugged, somehow when i was installing my new inlet duct for the turbo it became disconnected, not from the downpipe but from the other end. Where does it go? PLEASE HELP ME, I AM BEGGING YOU. I need vivid descriptions because I am obviously a newbie.

 

the 02 sensor lead branches off from where the BAC plug is (about 3" down from it).

 

also, you might have trouble finding it... on my car it was GONE and I had to rewire it!

 

My problem was that i broke the wire leading from the 02 sensor to the black connector to the wiring harness. I just spliced the wiring after cutting off the black connector, how will this affect my air/fuel ratio? I will fix the connector on sunday and check for vacuum leaks on my new inlet duct, ahh what is a good way to plug up holes on the TID and the Airpump lines?? I've used everything from a wine cork, to a metal bolt to plug vacant vacuum lines........I worked on this thing today from 2:30 pm to 9:30 pm straight, im so tired.......ahh but as long as Rex is running good, im feeling good.
