A while back I redid the 1980 wiring diagrams. I finally found the disk they were saved too when I had to reformat my computer. I have approx. 150 hours into making these from the original black and white diagrams. They are 100% color coded and easy to read. If anybody is interested, I can email them a copy, free of charge. I would post them on here but I haven't quite figured out how since they are PDF and quite large.
