Cheers mate....
That explains why theres no 12v wiring behind it then...
Got a switch on the dash for the fridge, only live when ignitions on...I guess it would still need a relay
Thick wire from LB goes to the centre of the relay under the dash, which is then feeding the 'extra' fuses.....
Looks like it never had a Zig unit, and the split charger seems to work....
Best leave it all alone!!!!
Cheers all!!
