'81 KDX250 wiring diagram

I have bought an '81 KDX250. someone has worked on the wiring and installed some Suzuki parts and there is no fire at the plug. I did a search but only find the diagram in the sticky for a 200, Is this the same? Also, will a CDI box off of a later model KDX work if I can't find one for a '81?

Also, where can I find swing arm bearings and fork seals for this bike? any sites with installation instructions?

Thanks for the help,
