Ya, I found mine right where everyone is saying and it is right there in the open once you take the back panel off. Super easy, you DON'T need to do anything inside the "convenience center" itself.
Looking forward to replacing my original pump with the new stuff on order!
Gotta say, unless you're a plumber, that piping on the back side is a real puzzle. T fittings, 90s, valves, pipes going everywhere...
