I assume you are using a toggle switch for your wipers. If so here is how it should be wired:

The center connection should be your power that is connected to your ignition and is only on when your key is on.

The top connection can be for your slow wiper speed coming directly from your wiper motor (I think the wire may be yellow)

The bottom connection can be for your fast wiper speed coming directly from your wiper motor (this wire may be blue or green)

You will also have a ground wire coming from your windshield wiper motor that needs to be grounded to your firewall steel frame.

That should get you where you have functional wipers that go off when your toggle switch is in the middle position, slow speed in the down position, and fast speed in the up position.
