My dealer's maintenance department really "hooked me up" on this one...
I took the camper in for its "annual inspection" back in November for it's "Forever Warranty"... while it was in there, I told them that the black tank indicator lights and the grey tank indicator lights were reversed... "black" indicated the level in the grey tank, and vice versa... and asked if they could fix it. "No problem", they said.
Brought the camper home, and put it away for the winter.
Today, I dewinterized, and found out that now ALL the tanks are indicating the wrong tank... they fixed it good for sure.
I need to find out how to get into that panel to change the wires myself and make it right... I tried pulling on the panel and I can't get it open, I'm afraid I'm going to pull the thing off the wall if I pull any harder.
How do you get into this thing? Mine is in a location where I don't have visibility on the left hand side of the monitor panel at all... but it looks like there is a little tab of some sort on the left side.
Help me before I break this thing trying to get into it. I know it can't be that hard, but I just don't know the combination to this lock
Here's the panel I have:
