I'm an erstwhile Rockster owner. My knees couldn't take it anymore, and I moved on to a GS. Still miss the old sled.
Anyway, came across a printed circuit diagram. I picked it up pretty cheap at a dealership some years back. So before I put it in the general flea market wanted to see if anyone here wanted it. It's free, just need you to pay for shipping. Don't mind shipping overseas either, but obviously that would cost more.
Post here or PM me if interested. Thanks!
