I know where the upper one is that you can see when you pop the hood. I know there's one underneath somewhere, but have no clue where it is.

Follow the exhaust manifold to the other side of the cat and you will find it. FYI, the upper ones go bad more frequently.

I have codes on both o2 sensors and a vapor leak.

This car has always been a little confusing for me. On my Rav4 I can find everything easily, and there are diagrams and pictures everywhere online. The MK3 it's like everyone who ever bought one hates it so much they don't post anything about anything on the car online.

Like the horn. I looked on how to replace the horn and all the instructions and videos were about taking the front fender off. I actually got stuck doing that because of two bolts on either side that are recessed in such a way that I couldn't figure out how to get them off. Then I figured out an easier way and posted a video on it.

It's easier to jack the passenger wheel, remove the tiny shield from below. You have straight access to the horn then.

Did you actually just say it's easier to jack up the passenger side, take the wheel off, take the shield off, and get to the horn over my video showing that you take a knife or screwdriver and pop the plastic cover off the front fender and can directly access the horn?

Your method involves jacking up the car, taking the wheel off, putting the wheel back on, my method involves a quick flip of the wrist with a knife or screwdriver.

Pretend for a minute that everything I know about cars is from Youtube or what someone showed me in person and that I have no idea what I'm looking at in the picture.
