Oh, you mean the link in post #16? Seems to be for the entire vehicle. Did you find schematics for the 2 pcb you want to use? Please post those. If they are detaile enough, you may not need to make your own.
Yes, I found multiple schematics for the 2 Steering Pad Switch pcbs, but I don’t know if they are enough. I searched for “Steering Pad” in the linked document and I attached them as a PDF below.
