Windshield Washer Motor Install Help

I am in need of some help installing a Windshield Washer Tank and Pump.
Can someone please show me a picture of the plug the gets plugged into the bottom of the pump. All my wires that come through the firewall ( Bulk Head ) are tapped up and not sure if the wire is there or not, so I am asking on the bulk head which wire goes to the bottom of the pump. Once I find the correct wire I can use my meter to check to see if the wire has voltage.

Here is a picture of the unit I would be willing to buy.
