Hello all, My husband replaced the pup battery this evening, and discovered that the electrical wasn't working. Upon closer inspection, he found that the wires were connected to the mystery part below, which was in really poor shape. He took it off and brought it inside to clean up, only to have parts of the connectors fall apart. He says he can re-wire without it, but is wondering what it is, and whether we need it? Thank you!! *Disclaimer* Sorry I am not better describing what wires were going where, but DH is upstairs with our screaming toddler while I type this (oh the joys of bedtime), so he's not in a position to clarify at the moment.
