Basically what I did was pull the dash fuse box out so I could see which wires went to which fuses and then traced those to the fusible links, each of which groups several fuses together. Some of the circuits, such as ignition and fuel pump are not carried in the dash box, but instead run through fuses under the dash or only through the fusible link itself. I do have a record of the fuses carried on each fusible link by color codes. I'll find it and post, but mine was a '92 and considering how variable Land Rover production was, I would still trace each fuse to its fusible link on your particular vehicle. Next. Once I had a map of the fuses/fusible links, I tied the wire that carried a group into the equivalent fusible link in the Discovery fuse box. i.e. the circuits which carry ignition would go to the fuse marked ignition in the Discovery box. Hope this helps!
