The attached pdf show the location of the relay box. Update: after I removed the fuse box and took it apart I noticed that the relays are soldered to the circuit board so unless you are good at soldering you've got to replace the whole fuse box. I saw another forum where someone had soldered a wire and installed a remote relay. I've got a 2006 sonata GLS and my fuse box was tan not black like shown in the post above. the part number on the fuse box is 91950-3k010.
