Wipers go backward

[03BlkZ]

So I was finally able to connect the battery to my newly restored 70 C10. I was ops checking some of the electrical since I re wired the entire truck using an American autowire updat kit. I had left my wiper arms off until I could make sure they were parked. Well when I turn them on they turn in the direction of moving the wiper down then come back and park. Is it possible I wired it backwards or maybe could I have put the control rods in wrong? Maybe the arm that connects the push rods to the motor? Any help would be great. Thanks!
