I replaced the blower motor on a Gaffer and Satler gas furnace. That part was easy... where I screwed up was not labelling the wires in the junction box. Now I can't figure out how to connect the wires. I have a wiring diagram that is hard to read, glued and stained to the furnace that I can't read. What can I do?

Long out of business. Can you post a picture? I would guess one that old is basic, single speed. Belt drive or direct drive?
