Replacing Elixir power converter with a PD9130 or equivalent

I replaced my 55 amp unit with a 9260, the 3rd pic that BoyB posted the one with the colorful sticker on top. The 9200 series is about as easy of an electrical install as I've seen.

It would have been as simple as cutting off the 3 prong plug so I could wire it directly to the circuit breaker and connecting the 4 large battery cable wires. But I ran into a small brace the tried to restrict my mounting plan. I persevered with a few minor changes. It's really harder to get the old unit out than hooking the new one up.
