Quoted from GSones:
Based on the "repair" to the board I'd be careful about just going based on wire colors alone. Who knows what kind of repairs / hacks have been done over the years. Here's some details from the Skateball Wiring Schematic that may help you sort out what's going on. I highlighted one pin just to demonstrate how to decipher the code. I'd grab a volt meter and run down each wire one at a time just to be sure.
This helps tremendously. Thank you so much. I now understand how to look at the schematic and figure out how it works. I was wondering how all these numbers and letters worked and what they mean. Big big thank you.
Heres my schematic. And using this and my meter on buzz tone I should be able to verify that the wiring is going where it should be. I truly feel like I learned something today.
