What Power Source Does Valterra E-Valve Electric Waste Valve System for RV Black Use

Question:

Where do you connect the 12v power for source? You need to tap into something. I dont think I have any open breakers/fuse spots in my electrical box.

Hey Vince, the Valterra E-Valve Electric Waste Valve System for RV Black and Gray Water Tanks # VAL95MB does need to connect to a 12 volt power source so you could run it to your batteries directly if that's an option?
