Help! 1968 Windshield wiper motor wiring diagram

[AGL]

I have a 1968 427 convertible that was built in September 1967. Does anyone have a windshield wiper motor/switch wiring diagram? The car has been restored but, in all of the manuals I've purchased, I have never been able to find a wiring diagram for the windshield wiper switch & motor. Any ideas? Thank you and Merry Christmas!
