Rear light clusters wiring

[dave1966]

Hi all.

Can someone please tell me why there is 2 black, 2 white, 2 green, 2 red, and 2 brown wires on the left hand side rear light cluster and what they all connect to?

Many thanks in advance.
Dave.

Supply power to the light cluster?

Question is too vague.

Also used as a junction block to go to the cluster on the other side??

Is the question "What are these different colours for?" ?
If so, remove the cluster and see what bulbs they are connected to.

Or is the question "Why is there two of everything and not just one?" ?
If so, probably one set is coming from the towbar connector and the other set is going on to the opposite side as Woodlands Camper said. Pull out the cluster the other side and you might see that it has only one set of wires going to it

Sorry guys for any confusion, its the rear lights. The right hand side has 1 red, 1 white, 1 brown but on the left hand side there are 2 of each coloured wire. I'm not used to repairing caravans, as I am more used to breaking them for scrap and parts.
