Hello, I had put this on the kENT SECTION, BUT HAVE BEEN ADVISED i MAY HAVE MORE LUCK HERE!!!!
I have just bought a rear fridge unit with a zig unit as part of the package, I thought this would be easy to fit in, thinking I just had to connect it to the leisure batterys + & - terminals, but there is a yellow & green earth wire that needs to live some where???

There is also 3 wires that come from the plug sockets that should go into the zig unit, again, I think I know where the red and black wires go (+&-) but it's the earth wire again????? I think I am just being a bit thick, but I don't want to blow my self up or my beloved bongo or anything else!! is there someone out there that can expain how to do this via the email?? ANY HELP WOULD BE GREAT>>>> CHEERS....
