Bobcat 763 C series hand controls

[TottenhamMark]

The hand controls on my Bobcat 763c series have 6 switches. Three on each hand control. The machine is old so the symbols that were there originally are worn off. Is there any place I can get the basic description of the switches and what they control. My manual does not have a description and operation. I looked through a bunch of wiring diagrams but non of them seem to match up to my machine. The problem that I have is some of the switches don't seem to work. A wiring diagram would help a lot. If I could find a wiring diagram for my machine and a "Hand controls for idiots" page it would be much appreciated.

I guess I should add that I got this beater machine and the hand control levers are out of the machine as well as the connectors are all de-pinned. I have a couple of pieces of scrap iron and a bunch of wires hanging out of them without connectors.
