I should have added in the PM ... If you have a block heater it probably uses the same 12V relay... swap output wires. Mine is next to the one for the A Hot.
PS: turn on block heater switch :B :B :B

Looked at all the wiring and put a switch so we could bypass the high low 12v switches - so now I have hot water on demand.

When the switch comes I'll replace and crack it open to see corroded switch?

Thanks again - really enjoyed the HOT SHOWER -:S .:h .:? .:B
