The fuse box is held together with just a few screws, 2 or 4 can't recall offhand. The fuse panel then lifts off. Most of the 30 amp external fuse update will be mounted to the left inner fenderwell. The wires will pass into the fuse box through one of the rubber grommets on the front end of the box, To install, lift the fuse block off the box, feed the wires in, attach the two wires to the correct fuse position and reassemble. I can't see anyone placing the 30 amp bar fuse under the fuse box.
