12v electric.

I just bought a very old TC. It was built locally and the guy is no longer in business. My question I where can I find a wiring diagram that I can use re-wire my camper. It has a 6 wire connector from the wiring harness to the camper. But it seems the original builder used his own diagram... I am finding lots of broken wires and have no idea what is going on inside the camper. I am hosting for the next month and hopefully will have time to work on a new wiring situation which is more conventional. Inside wiring setup so I can have a better inside wiring and run a new set of lights on the rear of the unit.
