rjc, I added a new fuse box, as a matter of fact I added two. On your original fuse box one fuse is supplied by the ignition switch and one is supplied by constant power. I forget which is which, top or bottom. But the one that has all the green wires on it is the one supplied by the ignition switch. I wanted all these green wires to have their own fuse. To tell which is which, one fuse will be hot only when the ignition switch is on. So decided instead of crowding them all at the original location, and some may not reach the new fuses anyway, that I would move the fuse box inside and splice the green wires longer to the new location. I spliced them out and pushed them thru a grommet in the firewall. I added a second fuse box inside as well for the fuse that is not on the ignition switch (I think that is the bottom original fuse but not sure). The fuse box supplied by the ignition switch is mounted on the bulkhead above the brake an clutch pedals. And the other fuse box is mounted above the passengers feet. (you can just barely see it in one of the pics). The second fuse box has the horn, radio, and cell phone, i-pad accessory plugs. I deliberately did not want these supplied thru the ignition switch so as to keep from added more current draw thru that switch. Hope my pics come thru, and hope this helps some. Dave.
