So far, I've found references to at least three different Mondial fuse box upgrade options. 1. One seems to be a refurbishment of the original fuseboard that requires you to send yours in. 2. The other seems to be an entirely new board that uses wires instead of traces, requires some changing of the connectors (so it's a 1-way job), but does not require you to send in your original board. 3. The last seems to be a combination of refurbishment of the original board + the addition of a new circuit. This also requires changing of the connectors and other wiring work, and also requires sending in your board for modification (so it's also a 1-way job) All of them are expensive but I think I also listed them in order of cost I'm sure each of these work and are good in their own right. I"m curious if people have a perspective on the pros/cons of these different options. I'm sort of leaning towards option 2 because I don't have to send in the old unit, it fits the factory housing, and still seems to be a big upgrade. Thoughts?
