FYI, I spoke to the service tech from Garnet at the RV Rally in Louisville about doing the same on mine. However, I've got a bad tank interface module on my coach and can't find a replacement anywhere. They are no longer manufactured. The SeeLevel system needs those modules in order to interface with the Aladdin system so if yours is bad now, or becomes bad sometime down the road, then the interface won't work. With that system though they do mount a local panel in your waste compartment that would still function.
I decided I'm just going to go the local panel system (about +/- $225.00) route, have them install it ($85.00/hr approx 2-1/2 to 3 hrs labor), and know that everything is right. They are located in Granbury, TX. I don't want to be dependent on finding obsolete parts to keep it working. BTW the unit with the Aladdin interface runs about +/- $450.00 plus labor.
