I have the same fusebox, but still hunting for a good place to mount it. Did you wire it directly to the stock fusebox or battery? If battery, how/where did you route the wires through the bulkhead? Truck looks nice!
It is is a 12 fuse block from West Marine. I ran two 8 gauge wires directly from the battery to the fuse block. The idea is to keep all electrical aux independent from the Lucas gremlins that may lurk. In the Disco I there is a plug in the firewall/bulkhead directly behind brake fluid reservoir. I pulled the plug and cut a hole in it to run the wires through while still protecting them from abrasion.
The BlueSea Fuse boxes are great, just keep in mind that they are not waterproof. Sinuhe's installation is a sweet spot!
Also, Sinuhe, if you end up keeping the rollers you might want to consider swapping to the Delrin Rollers which offer a 68% reduction of weight then the stock rollers, high strength, abrasion resistance, and heat resistance, and a smooth surface to protect your synthetic winch line.
The Rover is looking great! Love the pictures, keep 'em coming! :bowdown:
