I am guessing that plug is your power beyond outlet. Is there anything stamped or wrote on that plug outlet. The cat is still alive.

There are 'ports' on each side that have 10-12mm hex holes in. No writing I can see. So I suppose one could be a HP line as it is next to the line from the HP pump and the other side is adjacent to the return line.
