Water Heater replacement 72 Safari

[RichHog]

So I took out the water heater and off to purchase a new Atwood G6 unit with electric ignition. Red and blue water lines go in and out I take it that red is the hot water, blue is pass through cold.
From the original trailer manual it appeases that original didn’t have electric ignition, but next to where the heater was on the left side are two green wires laying on the plywood. On the right side is a brown one and a black not connected to anything.
Any insight on this? Thanks

Just guessing but wires could be for the black tank level sensors.

Good to hear from you again Lum.
Good idea, do you know anything about wire colors? Next up will be to replace the cracked black tank. Think somebody forgot to winterize this trailer.

Service Manual says black, brown and red.

So wonder what the 2 green ones are next to the w heater? I’ll meter them tomorrow and see if they have 12v in them.
