Red light on toilet

[Daragra]

Monaco marquis 44m 2018. We can not locate the controller box that apparently needs a yellow wire cut to make toilets flush. Really need help locating this box. Monaco and Dometic don’t know where it is. We’ve looked literally everywhere and had a mobile rv repair guy look for it as well with No luck. It will flush after we back wash it 1-3 times but only a couple times. Sometimes goes red without any usage.

Are yours macerator toilets or the Dometic vaccuum toilets?

In Newmars they've always said the dometic flush box will be within a few feet of the toilet. Right underneath in bay below. If a rear toilet, maybe behind a pull away panel or even behind a heating duct. Also, if you haven't looked really carefully tucked in behind the toilet (if your toilet has the open back with hoses/wiring.

I've read about them being behind TV's in outside compartments. Lot's of different areas.
