I have a 1996 f250 with the 7.3. It has the single large plug on the wiper motor instead of the two smaller plugs like the earlier trucks have. My wipers quit working and I could make the motor run by taking it apart and hot wiring it but it wont work when plugged into the truck as it should be. The windshield washer still pumps washer fluid when you push the switch but the wipers don't run then either. I can also hear the relays clicking under the dash when I push the button for washer fluid and when I turn the switch but no wiper movement. Hopefully I described the issue well enough that I can get some help trouble shooting this and hopefully a wiring diagram as well if our gurus have one handy. Thanks in advance!

Thank you for the diagram subford! I'll see what I can figure out but I'll probably be back with more questions on the topic hahaha
