So I’ve ordered the “on demand control Center” and not just the on/off switch (which is also sold separately) :) That explains the connectors on the two grey wires (ODCC) and also the two LED wires, these four should connect the the switch. And I am assuming the red and black wires will connect to the orange/white wires. (Old Biscuit, yes I didn’t mean “connected” , rather orange and white ...positive and negative, sorry about that. Lol I assume the orange is positive and white negative? Then there is the small green wire from the RV...don’t know what that is for. And yes the 120 I won’t be using and I have terminated that into the junction box that was already there.Suburban water heater replaced by suburban NautilusHey guys, I’m replacing my gas/electric suburban water heater with a suburban nautilus heater. The rv has orange and white wire connected to each other and a small green wire. The Nautilus has red black (positive and negative) , orange and blue ( marked LED positive and negative) and two light grey/blue wires marked ODCC Anyone know how to connect these wires together correctly? Thanks !
