Eberspacher Handiwash Wiring? - Hi, I've just got myself a Movano Ex crew van. It has a Handiwash water heater with taps on board amongst other things. Most wiring in the van has been disconncted for some reason, including the wiring for the Handiwash. It had one red and one black battery cable leading up to it as well as twin cable Red & Black. The only wire left in the unit itself is a little live wire and connector.

Could somebody have a look at my pics and tell me what goes where please. Or better still post me a pic of the wiring of one thats installed.

Thanks in advance for any help you can give.
