How do you change the engine and fuel relays in a 2001 Kia Sportage?

I have a 2000 Kia Sportage and the engine and fuel relays are under the hood. They are on the left hand side close to the finder well in a black box. There is a diagram of which relay is what on top. If you look to the right of the fuse box there is a clip that you push and the cover comes right off. The main and the fuel relay are the same.
