Wipers stopped working!!

If any upgrades was made the whipper motor has a ballast/fuse under the hood I think, but like 1968FormulaS340 said it could be a connection in you bulk head going to the fuse box, I would think there is a fused link somewhere, but I could be wrong. a test light would be my best friend if I had this problem...... I don't have any info on a 68 Barracuda for a wiring diagram ... is there one here some where we can share ?
