That is so cool. I knew that it was something simple, especially after seeing the pictures of that rats nest! Seriously, though. Rule pumps are the best, and as far as wiring, my boat looks the same, the harnesses contain lots of extra connectors. I think that a lot of the Epic electrical problems are due to exposed electrical connections. The connections to the MDC box should be cleaned. They get damp and corroded and cause faulty gauge readings.
