THOR #14127
Installed Garnet 709-RVC NLP SeeLeveL II Tank Monitor System in 2017 Thor Aria 3901

Finally got around to installing a Garnet SeeLevel II Tank Monitoring System into our 2017 Thor Aria 3901 this weekend. Installed the screen into the wet bay and pulled power from the house batteries via a pre-existing pigtail in the wet bay. Pretty cool system....seems to work well! I bought the model that includes the RVC Network connection on the back. Next step is to connect the SeeLevel to the RVC Network and then work with Firefly Integrations to have their software poll the RVC Bus for the tank level info vs. using the analog feeds from the existing connections to the PMM. One thing at a time...

Thats awesome.

I just added this to my long list of mods. My grey tank sensors are not working now. And my Black tank as messed in the past (before I added the Tornado Flush kit).

Im hoping its just a loose wire for my Grey tank. But I would rather have a more accurate reading for all of my tanks.

RVC connection

Did you ever get started with integrating the SeeLevel into your RVC network? I am having trouble finding any information about this connector, they say they use a "standard RVC" connector, which doesn't exist by RVC specs. Do you know what the pins are out of the back of the SeeLevel or have you found an wiring specs on the unit?

I have the 4 pin wiring specs ...but the real show stopper is the configuration/programming on the Firefly panel to grab the 'values' off of the RVC network vs. the analog pins on the PMM. They want a hefty $1100 to make the custom programming change for me and I haven't been willing to spend the money.
