DALEDEVON@GMAIL.COM Report post Posted June 29, 2013 I bought a new Atwood water heater. It has brown, blue and green wiring. My motorhome has red orange and white wires. Does any body know which wires connect to which? Helpful nephews are great, sometimes. Share this post Link to post Share on other sites
desertdeals69 Report post Posted June 29, 2013 You need to follow the wiring directions that came with the unit and determine what the wiring is in your coach. I would guess the red is hot and the white is ground, use a multimeter to determine which is which. Share this post Link to post Share on other sites
