What part is confusing? It will have 2 separate circuits; one for the 120vac electric heating element and 12 vdc control circuits for the gas and electric side (if it is equipped with the 12vdc/120vac relay).
How is the trailer wired? Are there 2 switches in the control panel area that say electric and gas for the heater? What do you have in the water heater compartment wire wise hanging there? Have you determined what wires have what (type of voltage on them) etc.?
