Westy Kitchen Unit wires to battery

[SouthEastWesty]

I have looked around at the wiki and threads here and on Brickyards I promise, but just confusing myself and they're are so many.
After a very small but heart stopping fire from the wiring at my leisure battery I am going to start rewiring and updating where needed. I have various diagrams and wiring advice I'm looking through but can't seem to find this simple bit of info.

Can anyone give me a simple answer as to which wires are which from the kitchen unit to the battery.

The wires are as follows.....
1) All white ......... On further investigation it seems that the early Westy units (like mine) have the fridge relay on top of the fridge and this wire is connecting it to the battery.
2) All Red
3) Red/Black
4) Red Yellow

Obviously if this isn't standard then I'm in for a longer/griefier time. Your help and any advice will be appreciated.
