Don't bother with the colors since Atwood and Jayco are different companies.
Grab the manual for the new heater and identify each of the inputs:
A) -12
B) Building ground
C) +12V hot at all times
D) +12V use propane to heat the water
E) +12 use 120VAC to heat the water
A and B may be the same
C may not exist.
Using your test light, DVM, VOM, VTVM or TVM find out which RV wires are what vs. frame ground. The control panel switches will help.
Then connect as appropriate.
