The black cylinder in the very top left of the engine bay is the wiper motor, and just to avoid confusion you can see it has a blue wire going into it...

The other black cylinder that mounts vertically to the firewall is the charcoal canister, and you can remove it. It always has red vacuum lines going to it. You can still see the mounting bracket where it was in that pic. Just cap off the vacuum lines that were going into it, one on the firewall and one on the throttle body.

There's nothing on the other side of the firewall for it either, at least not on an EF. It just pulls straight up out of its bracket, and it has a drain tube that goes straight down. Just take it all out.
