Sieg KX1

I've recently bought a Sieg KX1. The previous owner appears to have be messing around with the PCB,s etc and the wiring is a mess.
Does any one know if a wiring schematic is available for this machine. I'm especially interested in the wiring of the C11G pcb regarding the I/O connections.  

I have the C11G user manual. What I don't know, and would be usefull is the manufacturers wiring diagram indicating what wires are what, and where they fit on the C11G. I can work it out given time, but it would be far more conveniant to have a diagram. But it's not essential. The previous owner had mixed up the limit switch wires, and I've now rectified that issue, but what else has he done I don't yet know until I trace them all back

Andy,
I have the complete user manual that comes with the machine. I has all sorts of information, including itemised parts lists etc, but no detailed wiring schematic unfortantly. I will be powering up the machine soon, so hopefully from what I've worked out we should be somewhere near.
