What Are these for?

Hey everyone,

I've had my third gen for a few years now but it's always been in pieces. I've almost got it back together but I have a quick question for you guys.

On my wiring harness there is a few relays and such that bolt to the fire wall on the drivers side right where the harness goes through the fire wall. I am curious what these are for. If someone could let me know that would be great.

Here is a picture of the section I am talking about:

There was a wire going from that relay over to the AC area. I have removed my AC so I am hoping that's what it was for because I have no idea where it went.

That looks like a hack job from a previous owner. I would remove that aftermarket relay and check to see if they damaged any wires by splicing into things and then repairing as needed.
