Similar to Bama's suggestion, I'd recommend you fill one of the tanks first (either grey or black) and check where it reads. Then, dump that tank and fill the other tank, also check where it reads. We've seen reports on here before of some models having bathroom sinks, showers, etc... plumbed into black tanks. If you have access to a sewer site, you might want to also determine where each sink is plumbed. Drain everything, close both, run a single tap for 10-20 minutes, drain a tank to determine where that water went. Repeat with next tap.
Once all that's done and you've got confirmation about which tank is which, if you need to swap the lights on the monitor, you should be able to do it right behind the monitor. Just need to pull it off and the wires for each should be right there.
