Fresh Water Tank Sensor Problem

[RMcNeal]

My fresh water tank froze and busted back around Christmas while in WV when it got to -8 degrees for several days.
Camping world had my unit from January 4th until last Monday repairing sidewall cracks at the rear under both living room slides. This is their 5th attempt, fingers crossed.
Since they had it for so long, I had them replace the freshwater tank for me. It holds exactly the 54 gallons that the old one did and does not appear to be leaking, however the sensors do not work corretly.
When completely empty, they read correctly as empty. After 15 gallons of water they read completely full. I never get a 1/3 or 2/3 reading, only full or empty.
My guess is that the sensor wires for the full and 1/3 reading are reversed. I have not torn down the coroplast to look yet. Does anyone know the color coding of the wires for the freshwater tank? I found a RecPro video showing Yellow, Green and Red for the 1/3, 2/3 and full sensors, but I'm not sure if these are RecPro sensors or not.
