    Reflection 315rlts holding tanks

    Hi folks, I am going on three years with this trailer and so far minimal issues. One thing that has perplexed me is the holding tanks.

    The panel shows in this order, Fresh, Black, Aux, Gray1, Gray2.

    So here is my question…
    For the “Aux” tank above it it says Black2 and below it it says Gray3.

    I had to clear the sensors on my most recent trip due to an inexperienced child using just way too much tp, but that is another story.

    Upon my return I did a thorough flush, and it seems the “Aux” tank is indeed tied to the black which was my suspension. For all you 315 owners, help me by letting me know if this is the same on your rig. I am thinking this is a mistake.

    Mine is a 2020 version.

    Thanks

    If I remember right, our trailer came black=black, aux=bathroom grey, grey1=washer, grey2=kitchen sink
    I switched the wires, now black=black, aux=washer, grey1=bathroom grey, grey2=kitchen sink

    Thanks folks, for some reason like it is definitely a black tank not bath grey.

    Got them all reading zero now, going to experiment using dye to see which is which.
