My 2 Jack Russell's tried to catch a rat that went in underneath the caravan. They broke some black foam insulation, two sets of wires, as well as a white plastic corrugated pipe, all at the rear left side of the caravan underneath a black metal cover. The pipe appears to be connected to a small white pump. Does anyone have a photo / diagram of what the wiring and pipe connections should look like? 

How would I repair this?

Saw now that it is mostly connections of the aircon. Easy to fix.

About the wiring, I do not know??

In future to keep Rats away from your Caravan, place Moth Balls Inside and inside the Nosecone.

They will never come back.

The Moth Balls give your Van a clean fresh smell without worries the way forward.

I drive with a sachet of Mothballs in my vehicle's engine compartment and never had a problem with rats.

Neighbours engine wires were attacked by bush rats, but mine was safe.

Dennis, ek stel belang in die "mothball" idee. As jy se sachet is dit n tiepe sakkie met gaatjies soos  n lemoen sakkie idee of wat? My kop se die reuk moet seker kan uitkom uit die sakkie om die skade-makers weg te hou.
