I've taken the factory diagram and have cleaned it up a bit and using service manuals and assembly manuals I have gleaned info on the color code and have just about finished colorizng the diagram. Anybody interested in a copy just PM me and when it's done I will email you the jpeg file. I'm using this to re-wire my 49 3600' under restoration.
