Thanks for the info guys! It's an Atwood 6 Gallon Gas / Electric Water Heater GC6AA-10E.

10E version uses COMMON 12VDC to BOTH on/off switches then to circuit board.
Circuit board then allows DC to either ECO & Gas Valve for propane operation
OR to the DC Relay then allows 120VAC to the Element

SO.........
Have to have 12VDC Switches for GAS/Electric
12VDC from switches to circuit board (White wire/electric---Orange wire/propane
120VAC from a 15A circuit breaker to the AC side of that DC Relay
Yellow wire from circuit board goes to the DC Relay which is inside the cover on backside of WH TANK where element is

Here is info on 'conversion' see has 23, 24, 25

Here is a 'color' version of wiring diagram
