I lost my diagram a while back and was lucky enough to find a copy at E's Garage. Then their site went down and it's back up again. DNS issues or whatever it maybe I'll post up a pieced together version here. E's also one of our members at our forum and we wish him well.
Click on the image and it will link you to the full size item. After that, right click on the image and save file as.
Thanks again Eric and best of luck to you.
