Hi, new to the boards, and unfortunately I'm sitting here stuck at work for another several hours. I had to leave mid-exhaust install and I didn't get a chance to hook everything back up. My question is a very simple one. Where do the front o2 sensors clip onto the car? It's going to be dark when I get home, but I want to get it done tonight so I'd like to know exactly where to look once I get home, as it's causing a fairly annoying rattle. Thanks again in advance for any help.
